Done. Best of luck with your dissertation, from another alumni of the Engineering Dept at UCL (mid 90s).

A quite well-constructed survey, I thought - unlike some we've had here.

I've responded to your survey and, as has already been noted, congratulate you on an unusually well put together set of questions.

One thing, though: I think that you might be falling into the 'averages trap'. One question was along the lines of 'How many miles to you drive in a normal/average day?' I answered something like 20-30, because that's fairly normal for me --- which, of course, would make a pure electric car ideal, apart from its crazy price. But like most drivers I also need to go much further on occasion: in my case, I regularly make a 420-mile round trip, for which even a Tesla would be no good (if I could afford one!) but my Auris turbo petrol can do on a tankful if required. In addition, since it is nearly all on high-speed roads a hybrid would be pointless because it would be running on petrol pretty much all the time, rarely using energy recovery to recharge the battery and simply dragging around the extra weight of battery.

I suggest that instead of looking at 'average (mean)' or 'normal' mileages you should be considering distributions of extreme values, since it is these that will limit uptake of EVs as people's sole or primary vehicle.
