Public charging. Again Tesla win the day here. Their charging is comprehensive, cheap, reliable and incredibly easy to use. However for third party cars reliant on third party charging networks this has been a problem. My brother in law bought a Mercedes EV over a Tesla as he looked at Zap-map and saw thousands of chargers across the UK and assumed it wouldn’t be a problem. He lives in Salisbury, we live in Oxford and both my Wife and my Brother in law regularly visit their parents in the Scottish borders. When we drive north, charging is easy and we integrate it into a lunch or coffee stop, my brother in law has only tried driving his car north once and it was an awful experience, he didn’t have any accounts, apps or NFC cards to use the myriad of public chargers, which were few and far between. 

The situation is improving rapidly for third party chargers, but it is still an unpleasant experience and I wouldn’t buy anything other than a Tesla for the next few years for that very reason.

As for remote charging. If I wanted to drive the Sahara desert, Amazon rainforest or Australian outback, I would choose a petrol car every time.
