Tall SUVs baffle me. The purchasers of such things seem to think it allows them to see more but given the massive blind spots they generate in all directions around the vehicle I feel they are fooling themselves.
Do we need a rule regarding seeing the road 2m or less in front of you bumper.
@gembo Rather than absolute size restrictions perhaps you should consider volumetric permissiveness. You can have a slightly longer car on the condition that it is narrower. The circumference of the body could similarly be restricted.
