As above.
One is made to be quiet, efficient & work safely without requiring any care/maintanence in everything from torrential rain and 5 degrees to bone dry and 30 degrees.
The other is made solely to do one thing, whilst offering a basic level of usability.
On track the difference is huge. At 80 degrees the road tyre is 60 degrees above its average working temp yet the track tyre is just getting comfy...
