I have an idea for a Shift Viral Shift Car
 

Here is a brief description of it. The Shift Type Viral Shift Car is a Shift Car which allows for Kamen Rider Drive to gain Type: Viral. It allows for the use of Chaser's Viral Cores in the Shift Brace to obtain E-Circular. The look of it closely resembles that of a black hearse with with a silver skull on the hood of it.

I had some concept art, but I seem to have misplaced it.
