I am fortunate enough to have my own drive and charge point. As you allude to, public charging could be time consuming and hit and miss.be sure to keep us posted ref that range.
Took the wife's car for an MOT earlier - there was a queue of 4 cars in a line waiting to use the charge point. The front one was hooked up. Went back to collect the car @ 90mins later and the 4th one was just edging forward to hook up for a recharge. Might be a penny a mile - you may do 250 miles on one full charge - hope you have 2 hours spare in the day to recharge it.
