he got tesla mah, proton emas 7 tow tesla,
when proton emas 7 empty battery, tesla toll proton emas 7

confirm can reach penang in single charge, if cannot get another ev

nah, it's the infrastructure need to have the capabilities to support it rather than the car, for the car is just easy peasy pay more and you get more
but the infrastructure is just far to expensive, either way battery assisted charging or getting tnb to supply bigger electricity at the end you aren't going to get cheap electricity

nah it's less of a concern from the car, the cost from the car is minimal compared to infrastructure cost and restriction
other countries can do it because their infrastructure have plenty of buffer for future upgrade
however malaysia's tnb isn't the same, our buffer is minimal and it's seen as wastage
you just can't simply install ev chargers in highway / petrol station without upgrading the infrastructure

actually both can be made efficient regarless of speed

petrol engine can be efficient at low speed also, it's linked to how it's made and the rpm
but usually they make it efficient at higher speed if you want to have both then you're going to complain it's very easpensive

electric engine can be made efficient at high speed also same concept with petrol engin
but then you lose the advantage of boasting like no engin oil no gear box oil and ligther car (without battery included in the calculation)

ev fans will say fake news, no need oil change even brake oil also bla bla bla
