I do a mix. Sometimes BKK is paralyzed. Sometimes I've gotten out of a BKK cab stuck for 20 minutes in traffic and walked the rest of the way. (not with a suitcase though. I'm still a 70 yo backpecker). Being a born cheapskate (um, "Thoreau disciple") helps.
One thing, if you've lived here long enough you know the best ways of getting around at different times a day. A lot of times I'll take the very funky canal boats, the absolute quickest (and cheapest at 12 baht) way to get from Banglampoo (home) to Nana. Other times it's taxi or river boat (Chao Praya river) or even motorbikes, the drivers who are oblivious to traffic jams (wear your helmet and knee pads ). The only form of transportation here I almost never take are songtaows (ripoffs, usually rude, and out to screw touristos).
I get away with much of this because I'm retired and live there, and carry a backpack at the very most (but usually just a bellybag).
