With all the time, work and money that goes into building a thrust powered turbine car, should they be retired or could they be used again and possibly break more land speed records or are they retired because that is all the speed you can get from them/too dangerous to drive...? Specifically, Richard Nobles Thrust 2 and Thrust SSC and Craig Breedloves Spirit of America.

"I have marveled often at the thin line that divides success from failure, and the sudden turn that leads from apparently certain disaster to comparative safety." Ernest Shackleton, Antarctic Explorer, 1874-1922.

From the movie Dr. Strangelove, General Jack D. Ripper:

They have neither the time, the training, nor the inclination for strategic thought. I can no longer sit back and allow Communist infiltration, Communist indoctrination, Communist subversion and the international Communist conspiracy to sap and impurify all of our precious "automotive" bodily fluids."

First off, the SCTA will not allow (likely ever again) thrust powered vehicles (either jet or rocket) as they did in the early 60's.

You seem to mix up the use of turbine vs. jet. yes a jet uses a turbine but is a thrust powered engine.
Most proper turbine engines are shaft driven.
 
Turbine powered "wheel driven" vehicles ARE currently allowed in SCTA competition. There are currently 3 classes for such vehicles.

Lastly, the 3 cars you mentioned had all reached their useful speed range with little if any in reserve.

Nobles "Thrust II" according to his designer John Ackroyd Thrust II was in danger of flying within the next 10 MPH (it had a terminal speed of 650 MPH for the 633 MPH average) according to his calculations.

Thrust SSC had also reached its limits with regard to the friction coefficient of the wheels on the dry lake at Blackrock and the power available from the engines, albeit good enough to break the sound barrier setting the current land speed record at 763 MPH

As for Breedloves Spirit of America she too almost flew & major work was done to install larger front canards along with other aero mods, so Craig was lucky to set the record at 600 MPH back in 1965.

John Ackroyd also worried about Thrust SSC getting light in the front at speed.

Here is a picture of the team testing the automatic rockets that would fire IF the Thrust SSC got light in front.
