I don't want to sound arrogant but I'd say I'm fairly quick online.
Most of the fast guys will generally try to overtake the slower racers quickly but without hitting them. Hitting other racers only really slows you down.
I would suggest you use the braking line assist (if you don't do so already) so as not to brake early for corners. Most often if I hit someone slower it will be because they started braking too early for a corner.
As a general rule you don't want to move out of the way for people. Just be predictable - don't weave around the track, brake when the line says (its correct about 95% of the time). Most importantly don't move erratically while braking - it is very hard to change your direction while braking hard.
