just from a biological perspective, inertia, even if the craft can stop itself after going at that speed, your body is still moving at lightspeed in the craft, you'd be vaporized and splattered all over the ships interior when the ship stops. they're testing out a solar sail for space travel that would allow you travel at 1/10th the speed of light, but it's all theoretical.For all you physicists on here what are some of the challenges of making a warp drive?
