Honestly, even my Lightning could do 450 with one stop, and it’s not the poster child for high range. My model 3 would do that no problem and the stop would be half as long.

My back and butt beg me to stop every couple hundred miles anyway, so on a long road trip I plan for a lunch stop. Longer than 450 and I stop for the night or fly. But I don’t love road tripping no matter how big the has tank.
