There are YouTube videos of this technology in action. It's great during rain/nighttime driving. Personally, I see more good in this than bad. Able to squeeze into tighter spots, better visibility, and saves money by eliminating the cost of replacing broken mirrors. If it stops working, bus simply goes out of service. The previous comment is also something to worry about. I've only driven for transit for a year and a half so the change won't be too drastic for me but for longtime operators, it'll be harder to adjust.
