These Chinese/etc cars are perfectly licencable in the EU with very few tweaks required. Most of them would fit in the L6 category, some in the M category. Depending on which category the regulations vary. Motorway access will depend on which category, that was one reason why the original Smart design changed so much between concept and launch. Good examples of the higher end of this range are the Fiat 500, the Toyota Aygo (aka Citroën C1 and Peugeot 107/108), or for that matter the SmartForTwo, all of which have everything you are suggesting are absent. Just watch the Chinese improve their product designs to comparable levels, the pace of change is very fast indeed.
