Seriously, this is what Ford R&D money is going on now, is it? Apparently we've given up on making cars people want to buy (e.g. good fuel consumption, low maintenance, etc.) and now make ones that look like something from a Japanese version of Dragon's Den.
If you have your hands full, put things down - don't go kicking out randomly at a car which puts you off-balance, in the middle of the road, while carrying heavy shopping, and potentially damages your back and foot, while flinging up a metal door into your face. I have a car key (old fashioned concept, I know) and it's never been worth even 10p for me to be able to open my boot like this (and, as pointed out, automated closing of the boot is a recipe for disaster - dog catches head in it, child puts arm out to grab toy at last moment, scalping yourself senseless, etc.).
Plus, it's just more drain on the battery for no reason.
Want to shock me into buying a car because it's just such a great concept? Make car doors that *DON'T* damage other cars if you catch the edge. Make a paint-job that doesn't need a respray after a slight scratch. Make an exhaust that isn't hanging precariously in the most vulnerable part of the car for obstacles (e.g. speed humps, potholes, etc.). Make a car whose battery *CAN'T* be run so low that it won't let you start it (e.g. "emergency" single-start backup battery built-in but only activated by a big red switch) or even unlock the doors. Make a car that comes with it's own set of 20ft jump leads in the boot, under the spare tyre, and are permanently connected to the battery (isolation switch, of course) so you can jump-start / be-jump-started without having to lift the bonnet (and while you're at it, make it one of those that "senses" polarity/voltage and won't do anything if you touch the leads together accidentally). Make one that uses a type of tyre that *can't* be punctured, or warns you about alignment/tracking. Make one that has a fuel cap on BOTH sides of the damn car. Make a car bumper that can be replaced without having to spend almost as much as the damn car (and if you can do it with just a screwdriver and not having to get under the car, even better). Make a whole series of cars with different usages (from sports car up to 4x4) that use lots of similar parts so spares are cheap (business issues with this one, I realise, but about bloody time we standardised on tyre sizes / windscreen shapes / mounting brackets / ways to change a bulb etc.). Make a car where add-ons can be purchased and installed with zero expertise (and I don't mean lots of complicated stuff - just things like electric wing-mirrors with a standard mounting that you just remove the old and clip on the new to upgrade, or air-con units that come as a £100 module that you just plug in without having to have a mechanic (there's no reason that can't literally be a "plug-and-play" upgrade), or sunroof (pop out blanking panel, insert sunroof panel), etc. Let students buy a dirt-cheap modular car and buy modules for it as and when they can to get to a higher model. Hell, you could get someone the module as a birthday present, that way.
There are a billion ideas that could be put into cars. Not all of them are useful, sensible or practical. But for every crackpot idea you put in, I'll find you a sensible idea that's just as cheap and is of more use. (And, yes, some of my ideas will be considered "crackpot" too, but at least I don't claim it to be my job).
