Well that was really horrible. 

Are car computers ECC?  When all they did was engine management a memory
glitch wouldn't have been too terrible, but now that some of them
control automatic parking and other "higher" functions, and with around
100M units in circulation just in the USA, if they aren't ECC then
memory glitches in running vehicles would have to be happening every day.
