Aerodynamics lead car design to repeat certain solutions. The Czechs were applying most of the tropes on their wonderful Tatras. Below we have the 1955 603 (and a nice nostalgic racing photo, just for fun). Compare the Czech car with the 2005 Mercedes Bionic and you see some of the same features.
The general view of Tatras was that the handling was not their strong point. Violent lift-off oversteer is the chief hazard. Racing one of these must have been like playing Russian roulette with a cross-bow.
The 2005 Mercedes Bionic received a good kicking for looking too much like a fish. I like this car´s alien appearance. And fish happen to be even better than aerodynamic, they are hydrodynamically very efficent indeed. Too bad that motoring commentators have lightning fast knee-jerk reactions. We could have a very different looking B-Class if this one had gone over better.
