Also depends of the height you want to reach
A constant and/or violent honk code might be hard to handle verticaly
If you want it to go like "hop hop hop" maybe turn the horn facing the ground and give it a projectile with a damagetype 1, materail2 70 and a forceOnExplosion 1 or 120
(speedmod 0 for the jeep anyway...)
Not sure of the results at all
You can do a lot of stuff (as crazy as useless) with the honk code or forceonexplosion, like vespa wheelies, stoppies...i even turned a ZSU into a lowrider...
Test, fiddle, test, fiddle, crash, fiddle again, go mad, that's ssm life!
