Night racing

This is incorrect.

Hot tyres + hot track = lots of grip

Hot tyres + cold track = less grip.

It's not that simple however, as there is the potential to overheat the tyre and thus loose performance.

It is however a common misconception that cars run quicker on cold days, car generally run faster in warmer temperatures.

It's not a misconception, just perhaps misunderstanding - a car's engine performs better in colder air, even more so in humid air - winter fog does wonders for engine response and "get-go".
Of course, nowadays, with electronic gubbinsery, the effect is either more pronounced (performance-fueled engines; restrictive intake) or subdued (economically-fueled engines), not to mention that tyre grip is probably a more significant factor for most cars.

Either everyone missed the pun, or I am the only one who thought it was funny...

I just want to put one thing straight about tires; Wether the track is cold or hot only effects how fast the tire reaches its optimum worktemp, and how long it can stay there. A cool track means that the tire can have a longer run, but also that it takes a little longer to reach its working temperature. Cool or hot tracksurface doesn´t exactly effect how much grip the tire produces, but more when it produces it.
If we use LM24 as an example, teams usually go for a softer compound at night, simply beacause they behave about the same as a harder compound in daytime.

In general cool air mixes more efficiantly with fuel, so at night many cars get a few ponies extra, at least in theory. In fact, at Le Mans 24hrs, the consistantly fast laps (many consecutive quick laps) are usually during the nighttime, but the fastest laps are usually made in daylight.

Also when online, one driver could voluntary adopt the role as safety car driver and act as some sort of marshal when it all goes wrong especially during endurance races forcing a restart behind the safety car.
If they had the new SLS AMG FIA safety car at their disposal it might not even be such a bad job.

That is very good idea... but they should make it more harder to be safety car driver... lets say that you need to have 500 000 A-spec points in order to be one... and later they could include (in later patches...) some kind of school of safety car driving... very very nice idea! thumbs up! 👍 👍 👍
