about 10kV per cm i believe. you're only at risk of it arcing to your body if you're within a centimeter of the wire. and that assumes your body to ground is a good conductor (it's not)
right before the used car market exploded i got my manual Subaru for $3400 when it was worth about 10-12k because of a misfire. yeah it just had the wrong spark plugs in it :p
and it's about as dumb as they come. it has a radio, abs, and cruise control - no other driving assists or telemetry
but it's gas? it should be electric with lgbt lights
