They are also used in automotive as part of the Coldfire CPU series. But I think a lot of this usage goes back to the days where embedded CPU families had been a lot more fragmented, and companies usually picked one family of their favorite supplier (based on pricing, fulfilling the use-case, etc) and then just sticked to it due to code not being particularly portable. Since that time the amount of CPU families that are actually used shrank drastically, and it's a lot more likely that all of those use-cases just pick ARM.
