For what it's worth, your complaint seems legitimate to me. However, if there are only two routes to get to a freeway, that sounds like poor urban design to begin with. Street connectivity is a virtue, and suburbs are designed to avoid it at all costs. You want fewer routes to the freeway to fix your problem, but having more routes would probably be the optimal solution to balance both your street's interests and your city's. Given your description of the neighborhood, I'm guessing that's not even possible anymore.

Anyway, take a video of people barreling down the hill and send it to a city council member. Newspapers also like this sort of thing when it's egregious enough.
