Italian iGP

I know there is a bump on the start/finish straight.
But it shouldn't be losing you 10kph every time you come to it,
Driver clocks up 323kph halfway down the straight.
Once he comes to the bump speed drops to 313kph, then back up to 323kph just before breaking point for turn 1.
Surely it should only be costing you 2-3kph?

Maybe higher ride height is helping ?

The speeds it shows don't really match what's going on with the actual dots I think, so in reality they shouln't be loosing as much.

My drivers have a very low experience level.
There for the car is running higher and with softer springs, than a driver with a high experience level.
