I drive the Calgary/Edmonton corridor almost weekly. You don't need 400 km to get from Point A to Point B unless you plan on doing a lot of intermediary driving at either end or in between. Even then, the infrastructure - at some point - will be sufficient enough where you don't need to drive that long without a recharge. But it will be based on balance and time, and how fast/efficient EV's can actually become.
The point of adoption for an EV for me, at this point, would be:
- Range of 500-600 KM - basically the same "range" as an ICE compact sedan;
- Electric charging station every 100 KM or less (Calgary, Airdrie, Bowden, Red Deer, Ponoka, Leduc, Edmonton);
- Cost of the charge is less than a tank of gas currently (around $35);
- Time to charge is 20 minutes or less (I think this has already been achieved?);
- Cost of the car is less than a similar ICE compact sedan;
- Maintenance on an EV is equal to or less than an ICE compact sedan (on warranty);
Once all of these conditions are met, then I would be convinced to switch. However, there are other factors at play that would inhibit as well. I am a condo dweller, and as such I don't have an internal charging station at the building, therefore the infrastructure is not up to par. Additionally, I would be interested in having driverless automation, and that is only 5-10 years away on a mass scale - not that far if you think about things. Said EV driverless car also has to be able to handle snow/icy conditions, something I don't have enough confidence in yet. I wouldn't know how a driverless car could handle whiteout conditions with blindsiding traffic on the next lane over.
All this said, I think it's a matter of WHEN - not IF. This is coming and I am excited for it.
