I got the Supertones for one MAIN reason-
To wake the sleepy truckers up in front of me drifting all over the road!!!!
I've been run off the road three times by semi-trucks who either weren't paying attention or falling asleep.
Every third weekend I take a road trip from Las Vegas to Boise, ID to see my kid- horns and turbo are very effective in dealing with truckers- one to wake them up if needed, the other to pass them when legal to do so- especially when climbing a 7000 foot peak outside of Ely, NV.
Plus, how crazy drivers are here in Vegas I can let them know my displeasure when they pull stupid crap like pulling out in front of me and slamming on brakes or shimming up next to me trying to take my place in the lane I'm currently in because they aren't paying attention.
Next upgrade- Brakes!!!
