It's a good idea, just remember to drive on the right. Traffic is lighter than on the Thai side but more chaotic. Roads aren't as good, even in parts of the city. Don't be afraid to honk your horn, though don't use it excessively either. Just a single honk at a motorcycle cutting you off is fine. Gas/petrol stations accept cash only. None of them accept credit cards. ATMs aren't as easy to find as in Thailand, especially outside of the cities and withdrawal limits are low. Be prepared.
