The technology already exists and is in use in some places already, but what happens if a bus is running late? do they have to wait a few mins to recharge or do they risk not fully charging and leaving straight away? what happens in the charging infrastructure stops working due to a fault, do the buses just not run? don't think this will work on longer distance routes outside of cities unless charging points were installed frequently along the way which would be costly, not just for the installation but the maintenance and the risk of vandalism, technology is evolving very quickly and it wont be much longer until a long range battery is available for buses just like they have evolved to with cars, now able to travel greater distances to when they first came around, electric buses are still a new concept considering how long battery operated vehicles have been around but one day all vehicles will be battery powered, I hope it is a success
