Yes I have the Active Parking Assist and value it greatly. I can drive my car without technological aids, and have done for around 20 years without incident. I appreciate the Park Assist mostly when I am in unfamiliar surroundings. I work in sales, and often visit towns and cities I am unfamiliar with. Typically, always under pressure to get to a meeting at a certain time, looking around for street signs and venues, it really takes the pressure off trying to identify a parking spot big enough to park in, (and when there is a queue of cars behind you )and it most certainly enables me to park in spots I never thought possible !
I read up on a lot of reviews whilst hunting for my "ideal" CMAX and most seemed positive but dotted with negatives too. I've been using it since I had the car - 6 months and its only fault (extremely rare) is that I go past a parking place that the sensors don't pick up. Ironically, the few times this has happened, the space has been huge so no issues "going manual"
I have parked in some of the smallest spots I've seen, and the only worry is, I end up leaving others behind or in front with some serious steering wheel action to get out of their space !
As for being taught parallel parking, well I passed my test, but that was in a 1989 Nissan Micra, a far cry from my 1.5 ton CMAX 7 seater !
I don't see why any "gadget" that makes life easier should be banned, at least not for the sake of some old fashioned pride
As for crashing in to £100k's worth of Merc, I don't think that's any worse than "crashing" (I'd imagine more of a bumping action) in to a £10k car> Besides which, if I was rich enough to own a car worth £100k I'd like to think I didn't need to park it at the side of a road ,I'd have a chauffeur to drop me off where I needed to go !
Hope that's of some assistance
