If you're going that fast, you'll have to stop every 1-2h to refuel in just about any car, ICE or EV. On the one hand, yeah you might have to stop for a little longer in a Tesla, but on the other hand you're going to save shitloads of money: driving that fast is massively inefficient, so you're going to spend a lot of cash on fuel in an ICE, whereas the superchargers are free.
Heh. The BMW 535d mentioned has a 70L tank, and even on worst-case drives (sporty behaviour, not highway), it's quoted (by users) around 15L/100. On standard highway (not unlimited-speed autobahn, euro highway 120~130km/h) it's quoted (again by users) around 7~8L/100. edit: and do note: your 5~10mn refuelling break on a normal car brings you back to full range, on a Model S it's 170 miles not the original 260-ish.

250km/h for 2 hours on a 70 litre diesel tank in a BMW 535 would require > 73% efficiency of the engine, which car engines don't reach.
Calculations assume: Coefficient of rolling resistanc) = 0.01 Mass = 1700kg Coefficient of drag = 0.25 Frontal area = 2.2 m^2
...and those numbers are on the kind side to the car.
On the other hand, 150km/h would require Writing calculations is a bit tiresome, so I'm not going to worry about it unless/until someone provides some calculations producing significantly different numbers.
