(Hi. I am not a native speaker. And I try to change your sentence as less as I can. In fact, I have little confidence in my sentence. Let's wait together more comments from other people .)
It is clearly seen that in the European countries(,) the percentage of using alternative means of transportation rather than the car is higher than that in Canada, where people use the latter in a majority of cases.Note: the first comma is unnecessary. The second is originally necessary, but because your phrase
in the European countries is short enough, it can then also be left out while not confusing the readers.
My references:
1. An example sentence from
the dictionary:
"In Los Angeles many companies encourage their employees to use alternative means of transportation, rather than the car."
2. I didn't change it although I've read
a discussion about
a majority of cases.
