Masonry bricks acceptable as pavers?
If your base is solid the bricks will be fine in both places. With that said I have done this and after several years of parking my heavy work van in the same area there was a noticeable indent along the tire path. I had ~4" of crushed rock or shale and then maybe 1/2" of sand, I put the holes up and seeded with drought resistant grass in them (I saw the idea in a magazine for more green spaces). I thought it looked nice but in the summer I had to water my driveway to keep it green.
