Their regs are a bit looser than ours - have you seen the weight limits on their TRUCKS - my lord driving beside one of them bad boys is three time scarier than anything in US - especially when ya aint used to driving on the wrong side of the road (all the time - lol)!
They have FAR fewer personal injury lawsuits also from what I understand talking to the locals (state medical coverage so no you hurt me I sue syndrome).
I'm not even sure wher to begin researching the difference though.
but their law states :
In the case where a motor vehicle manufacturer has not specified a maximum towing mass, the limit is stated to be:
1.5 times the unladen or kerb mass of the motor vehicle if the trailer is fitted with brakes; or
The unloaded mass of the motor vehicle if the trailer is not fitted with brakes.
That COULD be part of it as the JK "mass" is right around there! (but funny thing is brakes are required around 750Kg (1560 lbs) well under our average 2500!

The Jeep wave - it means nothing. Now I look for the RearView wave. Anyone can cause a guy to readjust his rear view at night. But in the daytime when you roll up behind someone and they adjust their mirror to frame your Jeep straighter - THAT'S a compliment!
