I totally get that! I love to drive and see new things. If the experience is what you are looking for, I say 100% do it. For the MOST part, locals will just drive and flow around you. It’s madness at first, but then you get used to it. Once you get out of Bangkok, everything will be fine.
One thing you CANNOT do in Thailand is be distracted when you drive. Texting on your phone, playing with the radio, eating can all be a recipe for disaster. So I think my biggest worry would be trying to navigate since you don’t k ow where you are going. Looking at the map on your phone for 2 seconds to see where to turn next will easily cause an accident.
