In addition to not only pay for their own damage to the cars, they also have to pay for the damages they cause to the track and barriers.

Most insurances won't cover trackday damages without special policies, which are very expensive.

Good vido but do you think that some more grip on the tarmac at some points is in favor as some are skiding at some low speeds but looks like fun

People imagine that GT cars have a lot more grip than they really have.

Downforce does nothing at low speed (Low meaning low speed for a race car), race tires must get their rubber hot before they grip as they should and a cold track keeps the tires cold.

Race cars do not stick to the road as many believe, in order to be able to corner at high speed, race cars must have an unstable (twitchy) design and require constant steering wheel input. It is the driver who "finds the grip" for the tires and not the car itself.

GT cars are quite bad at low speeds and that's why there are so many videos of Ferrari and corvettes crashing taking off from a red light.

Germany ...cloudy skies and rain..

It looks as if some of those drivers shouldn't be allowed on the road...let alone a race track!

What a waste... Driving on a wet track or when raining (or even worse)? And those bikers on a wet track? What did they expect?

I think in some cases the speeds are faster than they appear.

#7 Either that or those barriers are very effective! Like big fluffy clouds!!!!

O that poor M5 at the very start
