Sometimes I wonder on this forum if people have actually driven cars IRL with no power steering.
Guys, a small sedan with little 195 street tyres and a small wheel is a WORKOUT at lower speeds. Yes once you get going the steering feels great and a bit lighter but it's never weak. And once you actually put some sticky rubber on it? Put it this way, no offence to the ladies but I know for an almost certain fact that my girlfriend absolutely would not have the strength to drive it, the steering is HEAVY man, there's a reason why power steering was invented.
But, on the other hand, what do I know, I've never driven a Caterham. But I would bet that at lowish speed the steering would be pretty heavy, then lighten up a bit at speed but never feel loose and unstable.
The ffb of the Caterham imo is WAY too weak to the point something feels NQR. Increasing caster and the ffb helps but it is still too light.
Edit: I am assuming power steering is not simulated in the sim which to my knowledge it isn't.
