I don't think that was implied. The speed of light may be faster, but nothing in the article says the vehicle will be travelling at light speed.

Indeed, from the travel times both to Mars and to the nearest star it appears the vehicle accelerates in this alternate universe to the halfway point, flips around and decelerates. While it would never break our lightspeed during a trip to Mars it would on the longer trip to Alpha Centauri.

It's not the speed that kills you, it's the sudden stop.
