I remember a Thai train slowing to a near standstill, followed by an excessive tilt to the side for a couple car lengths of movement, then back up to speed.

Also remember lines of Thai people being stopped by a guard with a machine gun for searches while my pale colored wife and I were waved right through into the train station.

I would like to go back to Thailand it was a fantastic vacation.

All the more likely to underestimate the danger.

We are not good at estimating the speed of large objects because so much of our perception of the speed of objects happens in "units of relative length over time". When a small dog walks beside a horse the dog will appear much faster.
