If I used a flagfall taxi from my apartment to the office, it would have been a 15-30 minute ride, depending on the light at Sukhumvit. I tried it. Scooter taxis got me there in about 2 minutes, because they could make a wonky turn that a car can't. I also tried walking, but that was even dodgier because there's no sidewalk for half of the 1km route.
