I have lane detection, blind spot warning, distronic cruise control, fatigue warning, automatic parking in my MB. It's all 'nice to have' stuff, but when I get back in the e53 I don't notice it missing, you just naturally become more alert which I guess makes you 'busier' behind the wheel.

I think the blindspot warning system is a great idea if the retrofit works well. For some reason I find the X5 has a massive blind spot on the passenger side. I never trust the mirror, in fact, sometimes I don't even use the mirror and go straight to headcheck.

I might get some of those aespherical mirrors first though, but keen to see your progress @bugbyte
