Worth noting that the average 'real range' of the current crop of electric cars appears to be well over 100 miles...

…which will only improve as battery technology improves. I don't know what the average distance Joe Public will travel to visit a zoo or any other public attraction is, but I imagine it is far less than 50 miles.
You have to accept that their physical range is different to the 'psychological' range. If you are constantly watching the dashboard as the range drops, you are hardly likely to risking running it to empty. Running out is tad more tedious with a car full of tired, irritable children on board, than just a walk with a can to a petrol station.
If this practically reduces all car journeys to a radius of say 30 miles from your house then clearly trips to Longleat, or Alton Towers, Burgers or Paradisio (where from the look of their car parks
many, many people come from further away) will not be possible. Quite difficult to do a foreign channel-holiday to France on the tunnel, too... Small country zoos such as us might rely on people from within a 30 mile radius, but most of the wider tourism industry does not.
This is a personal interest of mine (and will feature in one of the static displays we have planned for Hamerton, when and if, funding allows), and research will show you that despite the huge advance in technology the range of these vehicles has improved minimally since the early days of motoring. Remember that early American motoring post horse and carriage, although initially steam powered, was then pretty much wholly electric and the internal combustion engine being a late-comer which did not really take hold until Henry Ford bought out all the upcoming patents for opposing technologies in order to promote his own vehicles.
During German occupation of France in WWII petrol supplies were cut off by the Nazis. As a result the clever and resourceful French produced a series of passenger cars powered by lead-acid batteries, with performance quite comparable to some of todays vehicles. Google -
Breguet,
Pierre-Faure or
Peugeot... When the Germans realised what was going on they stopped the supply of the batteries, and the cars became human powered pedal-cars for the street, made by companies such as
Mochet. These in turn post war had small two-stroke engines fitted and gave rise to the French microcars, les voitures-sans-permis.
Residual values are a potential issue too, and to repeat, as mentioned here before, what I was told by our local Nissan dealer about the Nissan Leaf (the first 'modern' practical wholly electric car) which cost £40,000 new, less a £10,000 subsidy from the UK tax-payer. At 5 years old or more, these are un-saleable, largely due to the fear of the cost of potential replacement batteries, and the dealers buy them back in at £2000 each to be scrapped. Making the car a short-lived disposable product, instead of a long-lived repairable one is environmentally very questionable.
I have to agree with Ned and Jeremy Clarkson, the powering of cars by remotely re-chargeable batteries does have the makings of another evolutionary dead-end...
