While driving, humans assume that the road ahead is OK (at least without significant potholes, and in sunny hot weather no ice-patches). We would expect better of robots (i.e. if a human crashes because of an oil patch, (s)he's a bad driver; if a computer crashes, it's a million-dollar lawsuit).
Edit: a better solution would be to observe the behaviour of other drivers; if there is someone driving ahead of you, you can assume that the road between you and them is OK; if there's noone ahead of you, you need to drive slower and be more careful (that's how I drive at night). Once there's a critical mass of cars with cameras, cars could communicate road conditions automatically.
