this is more a statement than a question but it could be questioned by you guys?

recently I have observed many people attempting to fill their newer cars to the last drop possible. 1 actually sprayed himself with gas. a word to the wise, bad move! all fuel tanks use a return system in which the unused fuel from the injector system retuns to the tank. this fuel needs space. additionally there are filters in the system to remove vapor gases from the tank before releasing to the atmosphere. fuel can be running int these filters and cause a backfire igniting your car! have many of you done this or seen people doing it?
