I forgot to mention that some cannot be photographed in freeroam for some reason (Bronco, VW Bora, VW Golf, 3 x VW Beetles, Chevy Colorado, Mazda and some others).
Some of the vehicles I did capture in freeroam were the Ford F-150, Transit Van, Subaru Legacy and some others IIRC.
I actually made a highway run (ShareCode: 563 622 933) to enable me to capture some of the traffic cars, but some had to be captured while doing a road sprint.
Quite a few need to be captured while doing Horizon Stories too, such as Alejandra’s Flatbed Truck, Hot Wheels Monster Trucks Bone Shaker, Focus RS, Peugeot 205, Metro 6R4 (the ones with roof logos).
So they can be done, no joke.
Have fun!
