* Trying to make Highlander ICE stop and go
* Making acceleration slow for fuel efficiency
* Removing annoying commanded disengage beep
* Raised accel_max by 50% and commented on chime
* Testing if Highlander ICE can resume follow from 0
* Returned to 1.5 m/s2 for testing stop and go
* Prep for merging upstream
* Prep for upstream merge item #2
* Added Highlander ICE/Hybrid to Stop and Go
Also updated table of vehicles
* Rollback advertising stop and go for Highlanders
* Fix whitespace
* Interpolate ki/kp for steering PID loop
Very much needed for the Volt port: car ping-pongs with low kp
on high speeeds, and the loop is unstable with high kp on
low speeds.
Also, removes "number or array?" logic from PIController,
now that all the callers use interpolation ofr ki/kp.
* Pass speed to steering PID loop for ki/kp interpolation
* Remove unused numbers import
