Those work vehicles also retail in the $80K range, so not exactly a poor-man's vehicle either. But anyone who is buying them for work is also claiming back GST and probably FBT etc. dropping at least $11K off the price to begin with - quite a bit more than the EV rebate. "Work" vehicles are a lot cheaper.
Sure but the govt isn't subsidising ICE work vehicles more than any other business asset. And if a business bought an EV (or any vehicle) it would enjoy the same tax treatment, plus a celan car subsidy.
FYI my SUV cost just under 60k in 2020. At the time I could have gotten a Ute with lockable tray-lid and roll bar for about the same price.
