Usually it's impossible to block their access.
Now about getting my door ripped off, that might really ruin my day. Ha!
That's too bad. Our expressways here usually have large concrete devices and the break down lane is just large enough for one to pull over and open your car door to get out.
If you slide over about halfway into that lane it becomes impossible for these idiots to get around you. I usually try to coordinate this move with a trucker.
Of course one can always slide out of the way to allow emergency vehicles to pass.
