Default killing cars with high RF?

Hi,
What's all this business I hear people talking about blasting people's
car stereos or killing cars altogether with high-power RF? I run 2m,
10m, and 11m in my jeep and I'd like to sort out the fact from the
legend and find out what kind of power I can use without risking
damage to my jeep or cars around me. At what power level is front-end
overload to a nearby radio likely? At what power level is damage
likely, and to what componets?

I am currently using only 50 watts on a 5/8 wave (2m), 25w on a 1/4
wave (10m), legal 4w on a 1/4 wave (11m)

Thanks,

Some years ago I keyed up a 2 meter handi-talkie (maybe 2w out) with the
2 meter rig about a foot away from a Radio Shack 5" portable color tv.
The 2 watts of 2 meter rf caused the TV to self destruct! I think
something in the horizontal output section died. The TV was operating
at the time (it probably would not have happened if the tv was off).
The set was repaired by Radio Shack.
