What I want is some options:
1. A gentle toot to wake up the driver in front of me when the lights have changed to green and they haven't noticed.
2. A thank-you when someone pulls over to let me pass or who holds back to let me into a lane. Something like 'ta dum'.
3. A blast that will rupture the ear drums of an eedjit when they cut me off.
Can't be beyond the wit of legislators and car/bike manufacturers.
