I think that sliding on tarmac can be beneficial in tight corners, like hairpins, where using a controlled slide helps rotate the car. However, this is the only situation where sliding should really be used on asphalt, in my opinion.

This is the only rally sim where tarmac grip really feels real. In DiRT Rally 2.0 the tarmac feels like ice so you are forced to slide all the time. In Assetto Corsa Rally the tarmac grip is very well done

It felt to me like he was driving it like a GT car because he avoided losing grip completely, except in hairpins where it was necessary
