You're getting attacked because you simply don't have the facts right. Read the thread from the start and you would see the stats from Masters of Endurance 4h test race.
Ease of driving has to be taken out of the equation, a good driver can do consistent fast laptimes, no matter what the car is.

The moe 4h test race showed what an underdog xrr is. Fzr was at least 1.5s faster per lap and some could even do one stop less than the xrr's.
Best fzr had an avarage laptime of 1:49.79, while best xrr had 1:51.41.

Yet another feature that isn't needed. The tyres will get warm one way or another, be that driving out of the pits, doing burnout or swerving.
Therefore it's just a matter of a time it takes, doesn't change anyone's speed on the track.
If you claim that is a reason for you to dislike hotlapping, it sounds like an excuse for not being competitive.

ps. No race is won in hotlapping mode

I think the warping is more obvious with BF1.

Something seems to be wrong with the netcode. Even small private servers are lagging quite badly. Changing packets per second does not affect the lag.
Lag is shown as warping cars, the smoothness of movement has dropped dramatically compared to before-patch state.
