And to me that is total nonsense. I did not and would not operate a MC here in Bangkok. Unsafe to the extreme - almost all Thai road deaths are on MC - it may be safer as normal low speeds of Bangkok but it is far from safe for anyone. I seems OP is talking short trips - which are not that much quicker on MC in any case, As to the elevated/underground networks there just is no reason to risk you life needlessly. But as stated above - that is my take on the matter - understand you and others are free to disagree. But do not believe it is a true/false situation.
