If you cant pass someone for position clean, then you cant pass them!
The keyword is
passing! It is not called
alongside'ing. The attacking manouvre isn't complete until you are PAST your opponent. Having your front wing next to your opponents rear wheel is not "past".
If by attacking the car in front of you, you put yourself in a position where you are unable to complete your manouvre without your opponent yielding in some form, you're not making a pass, but causing a crash. If your opponent chooses to yield to avoid the crash you are causing, that does not make you great at overtaking.
You are the driver instigating the incident by deciding to attempt a pass that requires your opponent to do something you can't expect him to do, in order to make your attack succeed. If he doesn't do that,
YOU are still the person causing the incident.
So gung ho-style attacks at the last moment on the inside of corners that are so tight, that you can't expect to make the corner while
staying on the inside line and not drifting to the outside and effectively pushing your opponent off track is not "making a pass", yet these are often seen in F1.
Getting alongside on the inside on a straight, but having to brake first to make the corner, and thus losing that position again, isn't passing either.
You have to PASS your opponent and make the pass
stick to force him to yield. If you brake first and your opponent gets back ahead of you, he has PASSED you again, and
you have to yield.
These fairly simple ground rules was strictly upheld by these guys, and racing was probably never better!

b) Overtaking, according to the circumstances, may be carried
out on either the right or the left.
However, manoeuvres liable to hinder other drivers, such
more than one change of direction to defend a position,
deliberate crowding of a car beyond the edge of the track or
any other abnormal change of direction, are strictly prohibited.
Any driver who appears guilty of any of the above offences will
be reported to the stewards of the meeting
c) Drivers must use the track at all times. For the avoidance of
doubt:
- the white lines defining the track edges are considered to
be part of the track but the kerbs are not, and
- a driver will be judged to have left the track if no part of the
car remains in contact with the track.
So, how much room is "enough" room? If you have
part of your outside wheel in contact with the inside white line in a corner, you are still deemed to be "on the track" according to Chapter IV article 2c, and according to 2b you can't crowd a car
beyond the edge, by definition allowing you to crowd the car all the way
to the edge of the track.
So basically, according to the Sporting Code, you can push your opponent all the way to the white lines, and still claim you're "leaving room on the track"!
