More money. If I had a Model S, I'd need to have another reliable car for road trips. I know I'll get flamed for this, but long charging times, highway speeds killing battery range creating frequent stops, and crowded superchargers mean that to me, teslas are still city cars. For a tesla to be my only car, it would need to be able to recharge in about 10 minutes and have empty superchargers ready wherever I need one.
Same reason I might not buy the Model 3, although the lower cost leaves more money to buy a road trip ICE car.
WTH: I know everybody has their own perceived needs, but your statement about road trips is just plainly false. NOBODY, nobody drives a car nonstop for over three hours, especially on a road trip. That equates to about 180-210 miles. If you do, you have an incredible bladder control. People like to get out of the car and stretch their legs, hit the bathroom, and maybe grab a bite to eat after 1-2 hours of driving. And even though I know that some people have absolutely no patience, does taking a 20-30 minute break to charge your car really that much of an imposition? I know, you can fill up the gas tank in less than five minutes and then take a 20-30 minute break.....
People are traveling all over this country with their Tesla's and doing quite well, thank you. You'd better stay with an ICE if you have to charge an EV in 10 minutes and have empty superchargers waiting for you wherever you go. Get real!
