Sure, because the Tesla Roadster is half a car, and cost is no object. They literally took an existing car, and built an EV conversion kit, money be damned.

Making the first mass-market EV was going to take multiple years, no matter what. You need to engineer the entire car, at scale, and you need to hit a price-point. Tesla didn't have such an issue. I can't stress enough how much more difficult it is to make an affordable product than one where price is no object.
