We already know how to get arbitrarily close to 1C: just keep adding energy to the system to produce enough thrust to overcome the additional mass of said energy's source and the relative mass increase from getting closer to 1C. It's just not practical and the laws of physics forbid it from ever being practical.
Without a preferential reference frame, that's a nonsensical question. You can define your velocity to be arbitrarily close to C just be defining in relation to which inertial reference frame.
I would point out that this is "nonsensically pedantic." Clearly the frames of note are the one you begin your acceleration in and the one you end your acceleration in.
The more important question is with an Alcubierre drive, how do you decide which direction it was traveling. Since it is traveling faster than C, you can pick a reference frame where it goes frame A to B, one where it disappears from A and arrives at B instantly, and one where it goes from B to A.

what if instead of formula 1 we had races in orbit? this would push the boat out.

The reference frame of either the origin or destination is a perfectly good/useful reference frame to choose.
