I think he means that w P1 GTR it handles so well you can go flat out round and round and still not get over 242 fully upgraded. This is how all cars are (Regera can get nearly its top speed but only on LM as it doesn't handle the power well enough to go flat out around a speed ring.

I imagine things like wind, level above sea level, etc. contribute. Top speed is achievable in ideal circumstances with nonstop straight.
