Oh, they know it. When I lived in Germany 5-10 years ago, this issue was regularly discussed in the media. Some companies do try to adapt. E.g. Bosch traditionally delivered a lot of diesel-related tech, but they are also investing a lot in batteries and fuel cells. E.g. a large number of eBikes in Europe (probably a large majority even) use Bosch motors and batteries.

Only time will tell if it's enough. Of course, companies will try to stretch the transition as much as possible so that they'll have time to catch up.
