Public charging infrastructure, which in its current state is poor and real range are significant negatives. But it's the porkies that the brochures tell, that try to pull the wool over the eyes of the uninitiated.
First take the estimated range, well in the real world, expect around 80-85% of that number, worse in the winter. Then the recommended charging of 20-80%, gives you 60% of that range. So if you start with a 280 mile range, you are probably looking for a charger every 140 miles or so.
To rub salt into the wound, once you find your charger, hoping its not occupied and working, it most likely meant a detour from your route and then you will most likely be plugging it in and faffing around to start the charge in the pouring rain, as most have zero weather protection.
The Jazz when I fill up often shows around a 600 mile range, my less economical second (fun)car still has a range of around 500 miles. Life is too short to waste my time siting around waiting for a battery to charge.
I live in a small close of 10 houses and there are 3 Mk3 Jazz's and 2 Mk4 Jazz's, maybe its a start of a trend.
