You're In Business

The submission outlines a potentially useful concept for simplifying vehicle test drives but is critically undermined by verifiable false claims (e.g., 'most people have used my product') and a lack of operational data. The discrepancy between the project name 'Cartrast' and the submitter name 'SwiftShade', along with empty fields for users and revenue, suggests a lack of seriousness or a defunct project. There is no evidence of the logistical infrastructure required to execute this business model.

Description
Cartrast enables consumers to sample long-range electric vehicles, compact sedans, compact SUVs, midsize trucks, family SUVs, and minivans back-to-back without visiting multiple dealerships or waiting until the auto show comes to town. Customers can experience all the vehicles they're interested in on both the highway and local roads without salespeople on board and the hassles traditionally associated with car shopping.
