The well heeled ones ship their high end cars (Ferraris, Lamborghinis etc.,) over to London every summer to race around Knightsbridge and rev up outside the restaurants. The Police had to clamp down on them. Don't know if successful.
These ones coming here and renting Toyota Vios, Suzuki Ciaz, Clicks and Waves must be the Cheap Charlies of the Arab world. Not sure a THB2,000 fine would bother them too much though.
