i had the same problem with my front curb.after numerous attempts i figured out i could get out with no scraping if i "backed out" and turned the steering wheel as soon as the back wheels were on the road ,so at one point there were only 3 wheels actually touching ground..for me problem solved !

 

As the owner of a Bridjit, I can say it works great and is reasonably priced. Bought it on Amazon.
