> you are fine with it.

Why not ask me my motivations instead of assuming them?

I'm not fine with the range; I bought an EV to stop burning fossil fuels, my 24-year-old RAV4 was on its last leg, and there was a $6K bonus for trade-ins (my RAV4 would have been about $5k in parts).

Plus, the long-term cost savings kick in after about 8 years, which I blogged about at: https://dave.autonoma.ca/blog/2019/08/06/typesetting-markdow...

> Why you have to replace it with longer range?

Because I want to explore the interior of BC, drive across Canada on fewer charges, visit family, go on road trips, etc. Just yesterday I spent 30 minutes trying to charge my Kona. It's a long and boring story, but suffice to say our charging infrastructure here sucks, and is not as simple, quick, or convenient as "tap-to-pay" (with a credit card) at petrol stations.

> Should I be able to eventually replace gas tank with the larger one in my ICE vehicle?

FWIW, that is actually a thing you can do. It is mostly done for SUVs and pickups since the primary use case for the extra range is off-pavement driving and the upgrade is simpler.

Yes to both. Why not?

Batteries degrade, you know.
