Thankyou for all the feedback and bug reports so far.
I'm glad to say a number of bugs have been fixed up already.

[Gameplay]
- Happiness below 5 will now trigger HQ fines to manage the PR disaster, 0 triggers existential threats.
- The overactive tollworkers will now count average queue times much more slowly, allowing better control.
- Toll staff are now more lazy, they will remain in their booths on save/load.
- Deer are more nimble, less strong. They will no longer push cars but will happily step over them.
- Maintenance and Security will now patrol wider after completing a job
- The fast-worker trait now gives a 20% learning bonus for tollworkers
- To avoid doubling up, contracts with goals already met will not be offered to avoid instant-success.

[Bug Fixes]
- Car flow-rate is now saved and loaded - no more reverting back to 3 cars / minute :).
