In many countries, if you are not properly parked off the road, insurance will not fully cover.
If a lorry has its ass stuck on a railway crossing because there is not enough space ahead, are you going to blame the train engineer for not stopping on time?
Many transportation rules require that one has to stay clear of intersections, crossings, channels and main ways.
If you cannot fit, do not go in. True for big, true for the small.
