Looking back to why I paid up for my reservation a year ago, I just wanted Tesla to succeed in pulling off this amazing plan for mass-produced performance electric cars. The only way that was going to work, and others would follow, was if people like me bought one. Otherwise we'd be stuck with novelty cars like the quirky i3. I won't be changing my mind based on whether the car has a range of 220 or 250 miles or has a HUD display. If this car fails, they'll all fail and the oil lobbyists will send us all back into buying gas-guzzlers and the likes of Audi and BMW will stop their electric development programmes. If it succeeds, we'll have lots of options to choose from in a few years time. So, if like me, you've recently been over-concerning yourself with the details and starting to be tempted by other options teased by the competition, remember why you signed up in the first place and stick with it.
