One of the major problems with a turbine engine in a car is the lack of 
torque. This requires LOTS of gearing to overcome.
The other one is throttle lag. Any pilot of heavy iron will tell you that you 
don't just jam the throttles forward and expect the engines to respond; it 
takes several seconds for them to come up to speed. Recips respond nearly 
instantly to throttle changes. You can see the same effect with any 
conventional engine that uses a turbocharger; it's called "turbo lag".
