Arnie, you should inform the authorities of your sighting of a big cat. Unless you live in a remote area, it has probably been dumped by somebody who thought a big cat would make a good pet. Wrong!

Often such animals have had their claws removed and their teeth filed. They starve when abandoned.

(Learned this from the Department of Conservation.)

The fact that it crossed the road when your vehicle was within hearing distance supports the idea that it lacks the skills of a wild animal.
