Sometimes I wonder how you all get used to driving in a foreign land. For me, the Bangkok flyovers are impossible to remember by heart.
Ok, have to admit BKK roads/expressway/local roads/motorways/sois can be quite challenging even for Bangkokians.
During the early 2000s, while working for my former employer, was driving regularly between Thonburi, Don Muang, Suvarnabhumi (was called something else during that time) IMPACT, Sathorn and Rangsit etc.
Lost my way many times, miss the exits many times. Sometimes, keep missing the same exit many times. After a few times of paying tuition fees, will know already. Cos' some exits cannot afford to miss one, else have to go one very very big round.
Have to Jai Yen Yen. Nowadays, the motorways and expressways signs are quite good and in English too. So it takes awhile to get use to the roads. Only problems I encounter are some signs are too near the exit, so by the time you read the sign, already pass the exit.
