4 charges to do about 450 miles? i'm presuming you left home with it fully charged?Did from here (Sunderland) to Buckingham and back at the weekend.
Total doddle. Stopped each way at Chesterfield services on the M1. Each time just required a 45 min stop to charge. Were countless other options along the route as well.
Granny charged at a house down there over Sat night.
0 range anxiety.
