I wish them luck. However, Chiang Mai is already over-run with foreigners seeking a bargain life outside their home country. It will only inflate prices even more here in the north. Soon, locals will be priced out of their own city.
It doesn't shock me that many young (and older) Thais still ride their motorbike without a helmet. Which just shows a brazen disregard for laws....and an unconcerned attitude for getting fined.
As an expat living here in Thailand for many years, I'm still amazed at how little use horns actually get. Coming from America, it was a shock at first. While horn use in Western countries can sometimes be too much and abused....here, in Thailand...it's too little. Common-sense horn use is and always will be an effective way to prevent accidents.
