No you can’t, but Sven is correct - the driver who “loses” the corner is obliged to concede the place, or be responsible for any subsequent contact.
No he’s not, if someone is alongside you should always give a cars width of room, even on exit. To say that you have to have your front wheels in line with the inside driver is utter stupidity. Find me a single rule book that says that and you might have the tiniest bit of justification, but you won’t.
Ofcourse you can't shove them off the track
However you can't block someone's line either by keeping your bumper in the way and forcing them to brake extra to avoid contact. That's not sportmanship, that's just slowing everyone down and inviting trouble from behind to catch up.
Anyway, I just got bumped at least 5 times by a B/S driver, he never got a penalty. In a different race I'm on the racing line, I am ahead and the car on the outside turns into me at the apex, I get a 3 sec penalty for him bouncing of my rear bumper, he gets nothing. It's getting very annoying how it discriminates on DR.
But that’s exactly what that rule is saying! What do you think will happen if you just move to the outside of the track when someone is there and they don’t back out? They’re going off track and your rule says that’s fine, it’s the outside drivers fault.
And yes, you can block someone’s line by putting yourself in the way, it’s not unsportsmanlike because you’re slowing each other down, you’re doing it to compromise the other driver so you can overtake them more easily. It’s called racing and tactics, in the example were talking about the outside driver would have compromised the inside drivers line into the next corner giving them the better run onto the straight which is a perfectly legitimate tactic.
Also frankly I couldn’t care less about some guys opinion who has seemingly never raced before (at least he never mentioned it) and thinks he knows what he’s talking about with racing rules because he watches F1. Yes they do drive seemingly to that “rule” in F1 at times, but that doesn’t make it a rule of racing or right. You’ll also find plenty of examples of racing drivers holding the outside line and being given space by the driver on the inside even when they’re not fully alongside.
