Tourretes drivers.
If you have a desiese that causes you to make involentary movements then i suspect that you shouldn't be able to drive, supposing you stop at the lights to let someone cross and just as the person does so you're foot smacks down on the excelerator, the chances are it wouldn't be on there long enough for you to actually mow the person down as it were but still you would probably nock the person over, now supposing the person is an 85 year old man and when he falls he cracks his hip and has to be opperated on supposing he loses a lot of blood and dies on the opperating table.now all this is probably quite unlikely to happen but i suspect that it bears thinking about, for instance what guidelines are there on how one would prosecute such a case after all the person died as a result of injurys sustained when a car hit him.I remember the last time i posted something similar to this in a chat room one person said that I personally make her life very difficult, or miserable or something along those lines.
