We're not talking laptops and cell phones anymore. Recycling these big automotive batteries will make sense when 1TWh per year start coming in 30-40 years from now.
.
For longer trips a standardized series ICE gen on a trailer could be rented.

Why do you need inductive charging for busses at all? Do it the way busses (and trains) in many European cities have been for years: A pantograph connects to overhead power wires. If you have fixed routes, you don't even need batteries; otherwise you just charge at stops.

I think it makes more sense to have most EVs going around with 30-40kwh batteries and plenty of places to charge for those occasional trips than to haul around a 60+kwh battery just in case you want to make a trip (which you'll still probably need to charge on any decent trip anyway). It's because of the lack of chargers that a larger battery is needed or wanted to help with reducing range anxiety.
Perhaps fast charging costs are at a premium due to how new they are, but they do cost more than L2 chargers. Not only do they cost more to build (1-time cost), but they also have to pay demand charges, which are an additional monthly cost in addition to the amount of electricity consumed.

I was just thinking that it's more likely we get overhead power lines that our cars connect to than inductive charging.

If lithium batteries last 10+ years and there is some mandate forcing most cars to use them.
Where are the used batteries for these new cars going to come from?
Then if the plant is located on the left Coast it will cost a hazardous freight charge to ship the used batteries cross county for most locations, where is that money going to come from?

It would be nice but I don't really see it happening.
