"We can't do anything about an asteroid strike" Oh yeah?

...Various plans have been put forward to deflect incoming asteroids. For example, lasers or giant space mirrors could evaporate ices on their surfaces, creating jets that propel them away from Earth. And half-painting an asteroid could make it radiate heat differently on each side, slowly nudging the object off course...

Who is going to make the Barbara Striesands and John Travoltas of the world park their private jets (Travolta has 5) and drive a Civic?
