A someone who has been trying to figure out what vehicle to buy to tow my boat, I wonder how much of this is caused by weird tow ratings in North America. Towing anything with a car or small/mid sized SUV, and actually obeying the tow rating is a complete crapshoot. My current SUV is rated 1500lbs here and 3500lbs in the UK.
Pickup trucks are easy though. They come with massive tow ratings, even the small ones that my SUV outweighs and outpowers.
