In all seriousness, there's about 4 locations for top speed, most cars and series tend to have at least one of them. Best one is going the wrong way on Kemmel Straight (after Eau-Rouge) at Spa-Francorchamps, then it's the first section of the Mulsanne Straight at Circuit des 24 Heures, then down Conrod Straight at Mount Panorama (long downward straight after the top of the circuit), closed by Daytona International Speedway (Speedway is optimal, Road Course gives two straights, Motorcycle Course only has one, but it's the better of the two straights anyways).

If a car really doesn't have any of those available to it, then maybe Indianapolis Motor Speedway? Speedway is probably neccessary, I don't think the option given by Road Course would be good enough. Autodromo Nazionale Monza might be another possibilty, on the Road Course. Not sure which of the three possible straight would be best, nor the direction to take them in.

Some of the rest of the tracks may contain some mid-to-long straights, but the chances that none of the ones I've cited are available are incredibly slim.
