to my mind, its the most obvious place to put chargers. supermarket car parks were often always built for an imaginary capacity which would never be fully used, and in any case most people park close to the doors leaving the outer areas empty most of the time. Morrisons were the first to put rapids into their car parks and will replace those heaps of crap with MFG hubs in the coming years, Tesocs had the excellent but expired free charging VW/Podpoint tie-in but Sainsburys are actually rolling out high power hubs today. Asda are putting in machines at some sites, but mostly at their petrol station sites. Lidl and Aldi likewise have the same idea as Morrisons but are now woefully behind the curve.

Sainsburys have 7 hubs we can find information on, all opened from summer to this week:

Bristol Castle Court x7 (150KW kempower units) Bristol Emerson Green x9 Crayford x16 Exeter x8 Harrogate x8 Ludlow x8 Westwood Ramsgate x10
