Train horns

[h2co-pilot]

I oppose the train horn idea, not that it doesn't seem like a cool toy. However, for the expense and effort- how many times would you actually "toot" it. Not to mention the thought of possible litigation if applied during your daily commute.
For instance- someone cuts you off, you blast it and a Prep School Van full of privileged children get hurt because the driver got spooked and ran into the guard rail.
