System is pressurised so boils at a much higher temp than water at atmospheric pressure. Temp gauges are set to ignore fluctuations unless over a certain limit so will stay at 90 until a fair bit higher

It will get worse as the thermostat continues to fail. When temperatures climb over 250F the dummy temp gauge will start to rise from normal operating position. Be sure to turn the heater on if the thermostat fails completely while driving, it will help keep temps under control.

Good points. The heater blasting definitely helps.

OP sounds like tstat. I'd inspect the water pump too. tstat and water pump failed at the same time for me.
