Hard to say. Concrete is pretty firm after an overnight set, but not at all
strong. But if it is perfectly bedded, you *might* get away with a car
driven carefully if the underlying ground is solid which it should be if
it's had MOT hammered into it for the last umpteen years. Of course the next
24 hours will see a big improvement.

hence my pondering how I could put a lid on it to spread the wheel
loads whilst I get a reasonable cure - steel plate seems costly -
maybe thick ply would do?

If it were me, I might try to give the concrete 24h, then suck it and see..
Maybe barrow mix a short test strip to avoid wasting 4m3 if it all goes
pear shaped.

There's a substantial risk it will crack, but if it doesn't, the rest of the
150 yards becomes a much easier job.

How thick do you expect to pour and are you planning any reinforcement?

was heading for 4 inch average without any steel - worth adding some? £
£££?!
