your on a two-way street, then you could try crossing the road because the car can't drive on the other side.
If the guys in the car actually wanted to kidnap James or something, a road isn't gonnu stop them.
Of course the road won't stop them, that's what they drive on to begin with.

You can assume that at one point in time, traffic coming from the other direction will eventually become an obstacle for the car since they would be driving on the wrong side of the road after you have crossed the street.
