Ie highways, main arterial ect. That way range anxiety reduced & generally would have enough battery to get to the next charging highway. Although dread to think of the cost.

We still don't have 4 lanes running up the East Coast of Qld & stops when it gets flooded (how embarrassing) but there is only so much cash/ resource available.

One of the Scandivanain countries trucking companies was toying with overhead lines like trams (talk about visual pollution). Good idea on old tech? & only for smaller land mass / higher density population countries.

Whilst a good idea with current tech, will be obsolete where battery density increases ( holy grail looking like solid state batteries - how far away - yet to be seen - how typical 10 years + from discovery to commercial applications).

Gigafactories betting heavy in Lithium Ion 6 2 2 or eventually 8 1 1 although another mix of 9 0.5 0.5 had been touted.
Each causing its own unique issues.

So unfortunately this is where it will land for the foreseeable future, with incremental improvements.

I reckon wireless charging for small areas, e.g city busloops could be practical. For the broader range of vehicles I don't think they'd be practical at all

Considering that we can get a large car to do 400+ ks and a commmuter sized car to do 250ks with the current battery technology I would say that already makes inroad charging obsolete. We will get better ranges over the next few years that will make evs practical for 95% of Australians.

The wireless charging I'm referring to do is in parking spaces and garages. Instead of having to plug your car in, you just park over the charger and it does everything automatically. No leads to worry about. No forgetting to charge the car. The charge rate varies with grid demand etc.
