Favor major roads. Don't use a road of a lower classification to get between two of a higher classification.
Also, maybe this belongs in the map editing forum, and maybe it's already addressed in the wiki, but there are lots of alleys given the same weight as actual streets. There are some alleys in Pittsburgh that are all of 10 feet wide. They're meant for wheeling your garbage can into and maybe dropping your groceries at the back door.
Similar to your suggestion about truck routes, I think having a routing option of "fewer turns" would be of benefit not just to cars, but especially to trucks as they probably don't like having to make a lot of turns if they can avoid it. Someone suggesting a slider option for choosing what kind of routing to use and I think that's a good option. With the current 2 options and then a fewer turns option, you would have 3 sliders that are locked to equal 100% so that if you move one, the others adjust with it so the total is always 100%. If you wanted to have fewer turns and still wanted fast, but didn't care at all about distance, you might adjust them to 50/50/0 and it would find a route that is fast with few turns, no matter the distance.
And you're right about some alleys being very narrow. That really isn't limited only to alleys, though. For example, some old underpasses can't easily be navigated by vehicles from both directions at the same time. A narrow road option that could be applied to a segment may be valuable and could even be set to automatically place a warning icon as you come up to it. From what I hear, they are shrinking the width of parking lot roads, so they could do the same for any segment marked as narrow so it's also visual. I'd limit such an option to not allow it on major highways or freeways. Probably also prevent it on minor highways as well, but that depends on whether or not you can find narrow sections on minor highways.
