I think Toyota is saving the inexpensive EV's for when their batteries are there. Right now the demand for EV's is not there unless they are a Tesla. Ford is able to use the superchargers now so there is one hurdle but even Ford is sitting at 80+ days of supply with their EV's. The initial Mach 1 Mustang sold out but now dealerships are having a problem selling them.
I don't believe the consumer demand is there yet for even non luxury EV's.
