Okay, I think I have driven in quite a number of big cites. I grew up in LA county and drove there every day for about twenty years (ten in the '70s & '80s and ten in the '90s). In the '90s an 80-mile round trip to engineering school five days a week and later 100-mile round trip five days a week to work for three years.
I've also driven semi-trucks and cars in Los Angeles, New York, Chicago, San Francisco, Dallas, Houston, Miami, Orlando, Pittsburg, Baltimore, Washington and a (probably) most major cities in the US, except the NW & N.
I've been in Thailand full-time since '00, and have driven over 600.000km here, mostly driving from Prachinburi to Bangkok, but at least twice a week in Bangkok proper.
You?
