Yesterday (2/12) I was riding my motorbike down Sukhumvit Rd. at very busy time of 3:30 pm. A loud speaker advertising truck was driving at 5mph causing vehicles to veer into the other lanes to avoid collision with him. Why, in heaven’s name, is a guy advertising on Sukhumvit? We all know that these trucks are a nuisance in town and live with it, but on a high speed highway? Come on.
