Once the cost of producing these units drops it can then be considered for inclusion as 'standard equipment' (like ABS and many other once expensive optional features) on all their products which is where the real benefit of a cheap mild hybrid design lies. This would also do much more than Toyota could hope to do to reduce CAFE and on-road fleet fuel consumption in that timeframe and would probably go a long way (WAY longer than the ethanol guzzler push) to improve a very tarnished corporate image. Selling a few mild hybrids here and there won't add up to much in the big picture, but once the bugs and cost are worked out the strategy should be moving towards fleet-wide implementation as standard equipment.
