You raise some valid points. But the reality is different depending on where you live. I drive a UPS truck for a living, so I think it's safe to say I see A LOT of driveways. And here, there are so many people who do this that nobody cares. I saw many really old ones just today that are solid and stable. I have a background in construction and while I have not laid very much concrete, I could make it look reasonably smooth with a trowel. Now I would not do this in a new neighborhood, that's different. It would look terrible next to all the new materials. But this is an almost 20 year old neighborhood and my curb is already chewed up from 2 repavings. Bridjit will cost $500. I think that's excessive. I'd be happy to pay $300 for it if it spanned my entire driveway, but it won't. With an extra section, and shipping. It's $500. And someone could steal it.
