Thats why the curb are there, to prevent people from driving where they should not be driving.
I would assume this scenario are a daily thing there, so if anyone with a truck did that the ground on either side of the road would be plowed up and look bad in no time, plus you would probably soon have soccer moms stuck out there in their 4x4 suv with street tires that are useless as soon as the grass or dirt get just a little wet.
And not forgetting the 4x4 guys that did do that they will drag dirt and mud onto the street making it even more dangerous and probably cause even more accidents at the site.
Just becuz you can it dont mean that you should.
And dont get me wrong boilers i do totally understand you, but i think its just one of those feelings that we should do our best to suppress.
My first 4x4 the Mitsubishi L200 got stuck on a wet level lawn with 4x4 engaged and the diffs locked, that prompted me to get better M&S tires ASAP, and that did make my land rover driving friend shut up cuz with better tires my long ( ext cab ) pickup pretty much drove the same places the shorter land rover did ( 110 inch WB on the LR Vs the at least 130 inch of the Mitsubishi pickup )
Only places i dident go was the ones where i would have ruined my car due to the long WB and lower ride hight, and my friend fully acknowledged that and shut up dissing Jap 4x4 cars cuz he was a Land Rover fanboy.
