Toyota's only building BEVs using current batteries because they have to owing to government mandates (particularly in China, the world's largest auto market), not because they think they are suitable for the mass market now. And how can they be foot-dragging with H2 when they've got one of only three production FCEVs on the market, with plans to considerably expand their production? Toyota doesn't work on the "5 years is an eternity" timescale of U.S. auto companies, which is why we have large numbers of HEVs around the world now.
As to another poster's statement that Toyota and Subaru are loser companies, if consistently being either 1st or 2nd in sales worldwide (Toyota) or having increased sales every year for the last decade or so (Subaru) including the recession while being consistently profitable makes them loser companies, then I'd suggest that a recalibration of "loser" is in order. We can only hope that a BEV-only company will someday become that kind of loser.
Now, it may be that solid-state batteries never develop to commercialization, but some kind of battery that offers similar advantages (higher energy density, better cycle life, faster recharging, greater safety) will likely be necessary to completely replace ICEs for all types of trips. ISTM the current ZEV full replacement alternative to ICEs is PHFCEVs, assuming that both fuel cells and H2 costs can be brought down to competitive levels. That way, you get the benefit of a battery pack's higher efficiency for routine local use, while not having to deal with its disadvantages of high weight and slow recharging (or need it to provide heat in winter) for road trips. Something along the lines of the i3 REx, but with enough power from the stack to cruise at say 80 mph while handling hotel loads, enough H2 for at least two but preferably 4+ hours at that speed, and a battery pack with AERs ranging from say 20-50 or maybe 60 miles, although the latter is probably too costly/bulky/heavy to be worthwhile. Plus the necessary fueling and charging infrastructure, of course.
