You can make use of micro payments for this purpose, to pay for short charges. Other payment options have higher fees and will not be a viable option for the customers. I can get a $50 cent charge with virtually no fees with Bitcoin and this will work very well in urban areas, where you quickly stop for a drive thru coffee and a quick charge whilst you wait.
All this can be paid from the built in hardware wallet {Trezor} in the on board computer of the car. People just love convenience and would like a wallet built into their car. They can transfer money to it from their phone or even from work.
Later this wallet can be used to pay for parking fees and you can do this remotely from your smart phone. Hope to see a Bitcoin and Tesla partnership soon. Royalties for the ideas can be discussed in private. ^smile^
Thank you very much. I would love a automated wallet built into my car, because our local shopping centers have a parking system, where you receive a paper stub at entry with a magnetic strip at the back, and then you have to stand in a queue at a automated machine to pay for the parking fees. The challenges is as follows :
1. The card always gets lost and then you have to pay the maximum amount to get out of the parking area for a new card.
2. You waste time standing in the queue to pay for the parking.
3. It is coin operated, so the reader sometimes malfunction and you have to look for another machine at another entrance.
The wallet in the car, can automate this whole process and make my life easier. The shopping Malls can help to fund this idea, because they will not have to pay fees for the counting of the money or the fees associated with the collecting and the banking of the money from these old machines. ^smile^
They can even create a express lane for the people who has Bitcoin wallets and keep the old system for the people without Bitcoin.
