Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation and Principles of Consolidation The accompanying unaudited condensed consolidated financial statements included herein have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and applicable rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”) regarding interim financial reporting. Certain information and disclosures normally included in the financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes included in the Company’s Form 10-K filed with the SEC on February 28, 2023. In management’s opinion, these unaudited condensed consolidated financial statements have been prepared on the same basis as the annual financial statements and reflect all adjustments, which include normal recurring adjustments, necessary for the fair statement of the Company’s financial position as of June 30, 2023 and the results of operations for the three and six months ended June 30, 2023 and 2022. The results of operations for the three and six months ended June 30, 2023 are not necessarily indicative of the results to be expected for the full year ending December 31, 2023 or any other future interim or annual period. The condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries.
Principles of Consolidation	All significant intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Significant estimates, assumptions and judgments made by management include, among others, inventory valuation, warranty reserve, useful lives of property, plant and equipment, fair value of common stock warrants, estimates of residual value guarantee (“RVG”) liability and deferred revenue related to over-the-air (“OTA”) software updates, fair value of common stock prior to the Merger and other assumptions used to measure stock-based compensation expense, and estimated incremental borrowing rates for assessing operating and financing leases. These estimates and assumptions are based on management’s best estimates and judgment. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, which management believes to be reasonable under the circumstances. The Company adjusts such estimates and assumptions when facts and circumstances dictate. Changes in those estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods.
Reclassifications	Reclassifications Certain prior period balances have been reclassified to conform to the current period presentation in the condensed consolidated financial statements and the accompanying notes.
Cash, Cash Equivalents and Restricted Cash	Cash, Cash Equivalents and Restricted Cash The Company considers all highly liquid investments with an original maturity at the date of purchase of three months or less to be cash equivalents. Restricted cash in other current assets and other noncurrent assets is primarily related to letters of credit issued to the landlords for certain of the Company’s leased facilities.
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments that potentially subject the Company to concentration of credit risk consist of cash, cash equivalents, and investments. The Company places its cash primarily with domestic financial institutions that are federally insured within statutory limits, but at times its deposits may exceed federally insured limits.
Concentration of Supply Risk	Concentration of Supply Risk The Company is dependent on its suppliers, the majority of which are single-source suppliers, and the inability of these suppliers to deliver necessary components of its products according to the schedule and at prices, quality levels and volumes acceptable to the Company, or its inability to efficiently manage these components, could have a material adverse effect on the Company’s results of operations and financial condition.
Revenue from Contracts with Customers	Revenue from Contracts with Customers Vehicle Sales Vehicle Sales without Residual Value Guarantee Vehicle sales revenue is generated from the sale of electric vehicles to customers. There are two performance obligations identified in vehicle sale arrangements. These are the vehicle including an onboard advanced driver assistance system (“ADAS”), and the right to unspecified OTA software updates to be provided as and when available over the term of the basic vehicle warranty, which is generally 4 years. The Company recognizes revenue related to the vehicle when the customer obtains control of the vehicle which occurs at a point in time either upon completion of delivery to the agreed upon delivery location or upon pick up of the vehicle by the customer. As the unspecified OTA software updates are provided when-and-if they become available, revenue related to OTA software updates is recognized ratably over the basic vehicle warranty term, commencing when control of the vehicle is transferred to the customer. At the time of revenue recognition, the Company reduces the transaction price and record a sales return reserve against revenue for estimated variable consideration related to future product returns. Return rate estimates are based on historical experience and sales return reserve balance was not material as of June 30, 2023 and December 31, 2022. Vehicle Sales with Residual Value Guarantee The Company provides an RVG to its commercial banking partner in connection with its vehicle leasing program. Vehicle sales with RVG totaled $36.8 million and $55.5 million during the three and six months ended June 30, 2023, and nil for the same periods in the prior year. The Company recognizes revenue when control transfers upon delivery when the consumer-lessee takes physical possession of the vehicle, and bifurcates the RVG at fair value and accounts for it as a guarantee liability. The remaining amount of the transaction price is allocated among the performance obligations, including the vehicle, the right to unspecified OTA software updates and remarketing activities, in proportion to the standalone selling price of the Company’s performance obligations. The guarantee liability represents the estimated amount the Company expects to pay at the end of the lease term. The Company is released from residual risk upon either expiration or settlement of the RVG. The Company evaluates variables such as third-party residual value publications, risk of future price deterioration due to changes in market conditions and reconditioning costs to determine the estimated residual value guarantee liability. OtherOther consists of revenue from non-warranty after-sales vehicle services and parts, sales of battery pack systems, powertrain kits and retail merchandise.
Restructuring	Restructuring The Company’s restructuring charges primarily consist of severance payments, employee benefits, employee transition and stock-based compensation expenses associated with the management-approved restructuring plan. One-time employee termination benefits are recognized at the time of communication to employees, unless future service is required, in which case the costs are recognized over the future service period. Ongoing employee termination benefits are recognized when payments are probable and amounts are reasonably estimable. Other costs are recognized as incurred. Except for the policy described above, there have been no significant changes to accounting policies during the three and six months ended June 30, 2023.
Fair Value Measurement	The accounting standard for fair value measurements provides a framework for measuring fair value and requires expanded disclosures regarding fair value measurements. Fair value is defined as the price that would be received for an asset or the “exit price” that would be paid to transfer a liability in the principal or most advantageous market in an orderly transaction between independent market participants on the measurement date. The Company measures financial assets and liabilities at fair value at each reporting period using a fair value hierarchy, which requires the Company to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument classification within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. This hierarchy prioritizes the inputs into three broad levels as follows: •Level 1—Quoted prices (unadjusted) in active markets for identical assets or liabilities. •Level 2—Observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. •Level 3—Inputs that are generally unobservable and typically reflect management’s estimates of assumptions that market participants would use in pricing the asset or liability. Factors used to develop the estimated fair value are unobservable inputs that are not supported by market activity. The sensitivity of the fair value measurement to changes in unobservable inputs may result in a significantly higher or lower measurement.

Principles of Consolidation

All significant intercompany balances and transactions have been eliminated in consolidation.

Changes in those estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods.

Reclassifications

Certain prior period balances have been reclassified to conform to the current period presentation in the condensed consolidated financial statements and the accompanying notes.

Cash, Cash Equivalents and Restricted Cash

The Company considers all highly liquid investments with an original maturity at the date of purchase of three months or less to be cash equivalents.

Restricted cash in other current assets and other noncurrent assets is primarily related to letters of credit issued to the landlords for certain of the Company’s leased facilities.
