I am not sure customers will accept this, Tesla is a mature model in USA and we've not seen it there. Battery degradation is nothing like 10% per year, I can see EV owners asking the dealer to check battery SoH (state of health) and expecting that to be covered. I would for sure.
Roojai are already doing this and our premium for an MG EP+ was only 8,500 baht, we had to specify all regular drivers, we paid a surcharge to cover any occasional driver.
We have 2 countries with mature models, China & USA. USA aren't doing this, I find the Chinese article suspect, it's talking about one company only.
What I do think we'll see if insurance becomes an issue, is companies like BYD offering and underwriting insurance on their cars and freezing out the middle man. That would be no bad thing. There is no way that the Thai government will allow insurance companies to derail their go EV policy.
