In my opinion:
2nd prices will increase insignificantly only. EV market will collapse and all efforts of the government concerning charging infrastructure was a waste of taxpayers money.
Let's hope for the best that FRT exemption will stay.
Denmark has gone down that route, unfortunately. In 2015, about 2,800 Teslas were sold, while the first three months of 2016 - one 2 (two) Teslas were sold in Denmark. A handful of cheaper EVs were sold, since the Danish FRT is much more progressive than the HK equivalent.
This is how the Danish equivalent of FRT is phased in for EVs. It probably makes a bit sense -
it's just 10 years too early, should have been 2026-2030, not 2016-2020.
100% means 100% of the Danish FRT, which starts at 180% plus 25% sales tax. Yes, the sales tax is also applied to the 180%, so it's tax on tax.
The worst part of it is the uncertainty. Obviously, it's totally wrong to tax EVs this much, when the entire world agrees that CO2 and fossil fuel combustion must be slashed. Denmark is at the top with renewable energy, with more than 40% of electricity in 2015 coming from wind turbines. And that share increase every year on. Really silly that they cut the diesel car FRT, and increased the EV FRT.
I hope that Hong Kong politicians have more sense of responsibility, and are less in the pockets of the few very rich who really benefit from fossil fuel sales ...
