I'd REALLY like to fit a playback device with a recording of a truck full of live pigs locking up the brakes from 110 km/hr, played through giant loudspeakers in my engine bay.
But I'll settle for a truck air horn. I have a car air horn compressor, but I guess truck ones are larger.
Would one of these drain my battery / electrical system too much ?? I would only use it with the engine running, of course. I'd like to blast philistines who have more money than sense / empathy for other drivers, and see their heads swivel and rotate to try to find the truck bearing down on them.
Most of them have black Audi or BMW 4 wheel drives with air-con on and windows up.
My current horn only goes "poot", which is laughable.
I really don't care about the legalities of it.
