Electric Vehicle Design Plans

So I'm curious to see what other people's plans are for EV this year. I have come up with the following as all reasonable plans of design and capable of placing at Nationals given proper execution. Comment on which plan you will be going with and any differences or comment a different plan I have not yet thought of.
Note: all plans assume can bonus.
1.) Fixed Steering: An EV with a fixed angle of the front wheels similar to that of a scrambler car from 2014. Microcontroller calculates arc length of the curve and encoder is used to reach desired distance.

2.) Active Steering: An EV with a servo mounted to the front wheels and turns them at a specified point in order to pass through the cans and then mirrors the path traveled once passing through the cans in order to reposition back to the centerline. An encoder tracks the distance traveled along the pre-calculated arc.

3.) Dynamic Steering: An EV with a servo mounted to the front wheels and multiple sensors/encoders mounted to various parts of the vehicle that allows the vehicle to compensate for any run errors. Steering is adjusted during the run via a closed PID loop.

I haven't quite figured out all the details yet and any feedback on the above systems would be well appreciated.

Do we have to go back to the centerline after going through the cans?

That is where the target point will be located so yes

My idea is to use two motors connected to wheels in the front with rotary encoders.
