Point of reference.
richards car is a GT2 car. Which means (if I'm not mistaken) that it does not have an alternator. So if you do remove one of the lines to the battery, indeed, everything should shut off.
However, if you have an alternator, you have a different source for power- the battery just starts the controlling. If you remove the alternator, the regulator will not be very happy, but it will still run- we've jumped a car w/o jumper cables by removing the battery from one car, and putting it in the other, and keeping car 1 running all the time by making sure the positive side does not ground out.
In terms of building a race car, it does have some implications- with a battery only, one could get away without running fuses or breakers, because once a line gets grounded, it will probably drain the battery fast enough to stall the motor before the ground gets good enough to draw high amperage. With an alternator, you should run a breaker/fuse since that same small ground will not drain anything, and actually make the alternator work harder, to the point where the drain will eventually get really hot.
It's all relative in what you are working on.
As for the suspension, again, the POINT is to keep the tire square on the road ALL THE TIME. There are many ways to skin that cat, and both methods have their improvements, depending on the setting. Listening to you guys argue is funny, though...
(like Nizam said, for some people, nothing needs to happen, as all season tires will break away before the tires lean over much at all...).
