Somebody should do the numbers.

At 0.1c or higher, collision speed is high enough to make our ship and then ourselves radioactive. At less than 0.1c, it takes too long to get anywhere.

Jamming through space is not the way to get anywhere further than planets. So a Bussard ramjet is not a solution to interstellar or intergalactic travel as propulsion.
