That only works inside the solar system. The energy requirements to accelerate for a year are enormous. With 100% efficient engines, you would need something like a reaction mass the size of Jupiter.
On the plus side you quickly approach c. At constant 1g acceleration / deceleration, Andromeda is about 28 years away.
