This is a drastic underestimate. Going to M31 would take about 10M years at one-fifth the speed of light (since M31 is about 2M light years away). One-fifth the speed of light is 37,256 miles per second, or about 134 million miles per hour. So at 60 mph, it would take about 2 million times longer, or about 20 trillion years.
