I wouldn't buy without a test drive either, but having just bought a new car, I didn't test drive it at the dealership: I asked my neighbor around the corner if I could try his out, took it for a spin, and bought the car entirely online except to go to the dealership in person to sign some papers and pick it up...

Admittedly, you can throw a rock and bounce it off two or three Honda CR-Vs in my neighborhood.before it hits the ground, but I do know enough people with Teslas to try one if I wanted to.
