I have no confidence they will successfully produce an EV with the classic Toyota reliability because of the software piece.
It's completely wrong to call them the tortise, they are the hare. They took their nap, and now have a very different field to race on; one in which Hyundai is suddenly a strong competitor with years of practical experience - without domestic politics restricting them to daydreaming about Hydrogen.
I hope they surprise me, because I still love my 2016 Sienna.
On a related note, before I bought my Model 3, I went for a test drive at the Subaru dealership. The dealer specifically told me that, if I really wanted an electric car, I should go with Tesla because "Toyota will never get an equivalent charging network going here".
