it does not hurt anything at all on 2000+ vehicles. The starting procedure on the last generation of Bonneville is 100% PCM controlled. The PCM cranks the engine until it senses it is started, even if the driver already let go of the key. once you flick the key to start it'* all automated from there. Anyways, by turning it to "start" while driving the only thing you're doing is having the PCM only run systems that will work while the engine is cranking, such as ignition. The climate control, radio, and gauges will fall dead. It doesn't hurt anything at all, trust me on that.

EDIT: The reason I know about this is because I would at times get errors such as the ABS/ TRAC OFF message because of a bad wheel sensor/bearing. If I turned it to start while driving, everything was reset, thus getting rid of the error for a while. It can be usefull to do this.... for some things. It'* a heck of a lot easier than pulling over, shutting the car off, then restarting. If you wish not to try it, you don't have to, it'* just convenient if you ever need to reset a system on the car, while driving.
A couple things:
1. the car WILL NOT crank until it starts; it will crank for a short period, but only a few seconds.

2. You do realize that you would be better off if the light was ON than resetting the system when it comes on. The light comes on because its not working properly, and when the light is on it will disable the ABS and Trac functions. I dont know about you, but i dont feel comfortable driving with a malfunctioning ABS system, however if it is disabled (ie: light on) i feel perfectly fine with that.

yes, I know. However, just the fact that it will continue to crank after letting go of the key demonstrates the PCM is in control of the starter, not the person holding the key. Turning the key to start only serves as a signal to the PCM to let it know the driver wants to start the vehicle. It actually will only crank for 1-1.5 seconds. (plenty long for the car to start.)

Yes. However, when the car keeps chiming and the dic says " service stability sytem" that gets annoying after a few minutes of driving. If I can get the error to go away and get the car to stop dinging after I'm already aware of a problem, I'm all for it. I don't know how many times there have been flukes on these cars and the suggested advice is to pull over, shut the car off, then restart. Well, I was only saying that a full PCM restart can essentially be done without having to shut the car off. That'* it.

Then again, if you wanted to reset, couldn't you just shift to neutral, shut off, restart and then back into drive?

Well at least for people without your fancy high tech PCM abilities.
