I'm on a visit to the wine region around Adelaide, and am staying in Willunga. The trips I'm doing need a car, and the timing would be similar and the cost higher if I had flown to Adelaide and hired a car for the month

And I couldn't have seen the painted silos had I flown

And I couldn't have seen the sights of the great ocean road had I flown

And road trips in an EV are quite nice.

You can make good savings by not having a car at all, but that's not possible outside Sydney and Melbourne and probably Hobart
