Maybe because VW, for example, has actually skirted pollution laws, with intent. Or because PSA management publicly derides any effort for EV transition. Or maybe because Toyota has for 20 years falsely promised EV fuel cells/engines in the next five years, all the while happily selling ICE vehicles.

If you look closely at any big corporation management, they are all egomaniacs. Just not childish enough to publicize that fact.
