Merced, CA has some of the most fucked up on-ramps to the freeway I have ever seen, as well as incredibly dumb roundabouts and poorly labeled 1-way streets.

I absolutely hate driving around there. Even just going down to Fresno on 99 sucks ass once you get to Merced because the freeway is split there so you have to get off, go through city traffic, then get back on a few blocks later.
