Smooth canvas width animation

[tinypell3ts]

Hi 👋

I'm trying to create a vehicle selector. The user can select a vehicle by using the left and right arrows. Then, they can select the vehicle and it slides to the left of the screen and a form appears. I'm using react-spring for the animation. I'm having a problem with the width animation jumping.

Not sure my approach is correct but here is what I've got so far - https://codesandbox.io/s/vehicle-selector-iy98c
