I disagree to be honest Ronnie. You notice it more immediately then but it's still sloppy work and we should expect better, if I had to write or draw a story set in Germany I'd run it past Christian first to get it as right as I can (I have never been to Germany).
The point here is that all of it is wrong. Millar, Claremont and Rucka have made mistakes, like gun cartridges or nurses uniforms they are minor and nobody is perfect but they tried. Nobody on this book has tried. Not all UK police cars are Jaguars, mostly motorway police, but a lot of them are and that's better than completely the wrong car parked on the wrong side of the road.
