There is a very interesting point that I was never able to get answered. Malls, auto dealerships and others have TILE (1/4 inch thick) on their floors, and drive cars on them all the time NO CRACKING. I was actually considering the use of thin pavers or tile on the driveway, but could NOT get a straight answer from the concrete experts, or the paver/tile people. It would seem to me that either of these products installed with the SUITABLE bonding agent WOULD NOT CRACK as the load from the car would be transferred to the concrete driveway. However, this is NOT done, have never been able to find out why this type of installation is not done.
I am no longer pursuing this as we had the driveway stained and are very happy wit the result.
