No Toyota Tacoma…probably the most popular truck in many US states. No Ram trucks. No Subaru WRX, nor BRZ. Really neat concept, but I wish it had more US vehicles.

But you're right about the others --- this site seems to be Europe-focused.
I am currently shopping for a new vehicle, and this comparison could be very useful if it had the models I am considering.
Wealthy inner suburbs where white collar professionals live they absolutely dominate. Everywhere else people buy half tons because you get so much more vehicle for your dollar, the fuel economy penalty is marginal and with modern tech they're not really that much more unwieldy to drive.
However to add the 5th generation they would really need to split it out as a sperate brand to be correct, and if they do so, they should duplicate the 4th generation into the new brand.
