Lack infrastructure, really limited charging facility
Lack incentive, MY consume way too price sensitive, pay more to save the earth? what a joke
Lack awareness, MY consumer see EV, PHEV, Hybrid like see ghost, scare this scare that, most of all, scare of RV

Also need to consider the habit of Malaysian driver, interstate driving is common. It sucks to have mileage anxiety, which is a existing problem in China now given their EV adoption is really high. Not uncommon for them to encounter jam on highway and end up have to turn off aircon just to preserve battery for more mileage to the next charging station. And the best thing is, there's a jam / queue to charge their car. Let's imagine, driving from JB to Penang, have to charge mid way, and if you are unlucky, there's 2 char infront of you, each have to charge at least 30-60 mins.

But it's suitable if you only travel within city, and have charging point at home.

Also Malaysian dont have old car scrapping regulation, so it's common to keep your car for 15-20 years if it can run, but EV is never meant to be a 10-20 years car.
