Goof ?

Is it me or doesn't Honk Kong use the left side driving system like in UK (former British colony)?. China uses right side driving but not HK. If you cross from HK to the mainland you have to go through switch lanes. So technically , they should be driving on the left side , right ?

I get it that the scenes weren't shot in HK , but if you block the street, might as well make it look like it's in HK ?

Note that this ain't a critic, the serie is awesome, I just thought I'd mention that ;)
