Because in the US we like the thought our cars doing anything. I may get a camper, I may get a boat, I may take that once in a lifetime off road adventure through Colorado and Utah, I may have 4 kids and 3 grandkids and take them all on a cross country road trip, I may need to take 4 co-workers to lunch.Reservations aren't orders Ram like scout has a pretty rendering but last time I looked no one is taking actual orders. I think whoever is the first to offer test vehicles and takes orders will do well with the Erev version. But I think the Erev Frenzy dissipates in 3 yrs once batteries allow longer range. The Erev then is desirable to a much smaller market. Why own an Erev if you don't tow or have daily long road trips. So time matters as to who's first but manufacturers know EREV's aren't the long game EV's and advances in batteries are the holy grail.
