I do 20,000+, mainly on a commute and have always driven a smallish car for this purpose - albeit a Diesel with a fairly long 5th gear. I'd be happy to go to electric now that they are finally beginning to have enough range for my use* but leasing or PCP options at 24,000 miles (to be on the safe side) are very thin on the ground or outlandishly expensive. Normal HP might work for me, but one of the things still holding me back is all the unnecessary technology. I want a car I can step into, start up and drive, with a radio to listen to, a heater and air conditioning. Little more than that. I really don't want a "connected" car which wants me to install an app on my phone, or one with a massive LCD display which blinds me at night**, removes functions which should, by rights, be on dashboard switches to a menu system three levels deep. I'd even be happy with a totally unnecessary manual gearbox connected to the electric motor***. Of course, many non-electric cars are also going down this route, but it seems as if all electric cars are built that way.
There are companies which will convert any old car to electric, and I am sorely tempted, but the conversion cost is almost as much as buying a new car, and performance (particularly battery capacity) might be a compromise.
*It's a difficult one. My commute is 100 miles a day (though I don't work every day) with no opportunity to charge while at work. If I had a car with a headline 300 mile range but an advisory that for best battery life you should only charge between 20% and 80% (I realise some battery chemistries aren't that restricted) and use high-speed chargers sparingly, instantly the safely usable range is 60% of 300 = 180 miles. Stick that in the manufacturer's range estimator for a winter commute with lights and heating on and at mostly motorway speeds and 180 miles reduces to perhaps 120 miles. Add a 20% contingency to my commute distance for the times where I have to go home via a different route (which is slightly longer and a great deal more hilly and twisty) and my commute becomes 120 miles. And that ignores battery degradation over time. Things are getting there, but I'd feel safer with a headline 350 mile range and/or a 10%/90% recommendation, and those sorts of cars are out of my league at the moment. Hopefully by the time my current car dies, electric will be a viable option.
**Even the smallish displays in our current cars are a problem on this front, though the one in the Sandero - which is low down on the console and when switched to "dark" does not light up again every time you change volume on the radio or select reverse gear - is far better in this respect than the one in the Berlingo which does both of those things
***I can't say I have vast experience of electric cars, but some of them seem to make quite horrid whiny noises at slow speed, and horrid whirry noises at high speed. Couple a gearbox in line and you could run the motor in the middle of its RPM range and reduce both effects.
