You are fully entitled to your opinion but the data shows very little overlap between the groups of people who buy new cars and the groups of people for which $100 is a significant amount of money.

Tesla knew the $100 reservation was too low to show serious commitment, and this was intentional for two reasons:

1. to float an interest free loan

2. to manipulate investors
