I would love to have a train horn. They warm my soul. The horn on my W22 is pathetic. Not sure why they didn’t just do a regular truck horn. It sounds like it belongs on a Prius.
However, having been near a car it was used on by a pickup truck and watching the panic and confusion that ensued by the recipient I realized it wasn’t going to get the drivers attention in a useful way. Lol they almost wrecked. Which would have hampered the progress of that honked at them.
So the question is, if they are dumb and need to be honked at are they smart enough to process the train horn and the thing about to run them over not being a train.
plus it startles the crap out of them....round here they are likely to take a bat to your vehicle.
I had a 69 Toyota Corona that had a truck horn (wish I had it now) and it left people looking for something bigger, I was invisible.
