Given the multitude of problems facing California this is an asinine thing to focus on. Rather than hoping for a celebrity mountain lion in your neighborhood you should probably focus on the problems endangering humans in your state.
I say this considering a friend who once lamented the early space program was a waste of money, as he wore his advanced polymer clothing at work on microprocessors and GPS satellite and RF communication advances.
It felt pretty ironic.
It’s not like the LAPD is going to be ushering mountain lions across the highway. And biologists/environmentalists aren’t going to be fixing crimes of poverty.
Moreover, each time there is a car crash, somebody in the road must allocate resources to clean and deal with it. Call the police, ambulances... This is expensive also. Less collisions for the city means having more money for another needs.
