Seriously, non-current-owners.
Go schedule a test drive. It's unlikely in most locations that you'll get to take a spin in a Model X just yet, since those (at least in my area) are for reservation holders right now....
but go take a ride in a Model S. Tell them you're a Model 3 reservation holder. They'll be very happy to "nerd out" with you on a test drive. Dave in Natick was fun to ride with, he genuinely enjoyed seeing my wife and I get all excited about our test drive, and since he put down his Employee Reservation, we mostly talked about the Model 3.
I figured it was time to "get a feel" for EV driving, and in a highway/surface road mix, it wasn't that difficult. Probably helps that the wife already has a CVT, doesn't feel that much different....ok, except maybe the acceleration.
I even let Autopilot handle ~3 miles. Exciting stuff.
Go schedule a test drive!! (we're probably going to go back at least once more, to let the wife get some seat time.....and of course if they have a "Meet the Model 3" event for reservation holders.)
