I've been doing this for years. TBC - it doesn't eliminate the need to check your blind spot anyway (as many have mentioned) - just makes it more likely that you catch something moving unexpectedly into your blind spot, or you catch it before turning to look. Also, the positioning is difficult to get used to, since you kinda have to trust it blindly (you can't get a good idea for where it's positioned based on seeing the side of your car) and then also it's just awful positioning for parking. Not to mention, anyone else using or sharing your car will complain to no end about the weird mirror positions.
