This is the problem with the motor car: what does it replace in a person's life? The steam train replaced long stagecoach journeys and the pony express. The electric telegraph replaced letters that took 3 months to send by ship.
If you think a motor car replaces my horse and cart, you're nuts. If you think the motor car will carve out some new niche in my life that I never thought possible before, you're even more nuts. Suppose it focuses on leisure travel (likely) - do I really need a $40 horseless carriage to go to the county fair?
The only people who will line up to buy this are rich New Yorkers with more money than sense, end of.
