here in FL on the major highway in central FL ( I-4) they have these trucks running up and down to assist broken down motorists.. aka The Road Rangers.. they have everything.. Winches, tow lines, jump boxes, 5 gallon jerry cans of diesel and gasoline, light bar, a sign warning motorists, flood lights, flashers.. etc etc.. they help a lot with stranded tourists too.

everyone should get the w210 wheel chocks from the dealership.. 20$ goes a long way.. plus they are heavy duty

last week I put them behind my rears while changing my wheel/tires to the 8 holes... I forgot I put them there and when I backed away I was like.. why am I not moving.. and put a little more pedal down.. then I went up and over them

boy was I surprised, they were still folded in the up position and had dug into the concrete.. if they can survive that they are good in my book
