Strange because PHEVs should be their main focus, since ICE work, oil changes, etc. still mean business as usual after the sale. For pure EVs, though, not so much.
Remember instead of 2 or even 3 times a year of oil change, PHEV usually only do 1 oil change a year if that. Also there is very little brake work to do due to regen reducing wear and tear on the brake, same for transmission work
