How would I make completely new UI for this? Like how would I script it to destroy the old one and add the new one? Please help!

You need to the disable this boolean on the VehicleSeat.

The rest is design.

After that though, how would I get the current speed or max speed of the vehicle to put in the ui?

Sorry if i’m necroposting or late but,

You can use the A-Chassis Interface properties to define the speedometer. Like TCS, Speed and that.
They’re loctated in the Values folder.

Also for anybody who will try in the future, being here.
