Parts for building an electric mini car(not street legal).

I would like to build a smaller mini car, about the size that kids would drive and I'm not looking for it to be street legal. Most of the posts on here are for conversions, but I want to do this from scratch and design the frame/chassis myself and buy the rest of the components. This is my first electric car project, and so far the parts I think I will need are. I would like to make it a sports car/Corvette style, and I have experience in 3D designing the frame & chassis, so I am not too worried about that.

Motor Controller
Steering system

I'm sure this is not a comprehensive list, so please let me know if I am missing something crucial. I have had no luck getting a guide on building one either, so if you know of one I would appreciate that.

I heard about CAN Bus's being needed to get for example the battery level from the Battery Management System. Is that what you used?
Canbus just adds a layer of complexity you don't need. Many bms's have a bluetooth app for battery SOC, discharge rates etc. Can bus is important for road going modern automobiles, But DIY evs have been built without can bus.

I get what you're saying, it's not really for kids, it's for me to use(23) and a younger cousin who has been asking(18) for a smaller sporty looking car that we can play around with. There is this ginormous open unused lot near my house where we want to use it, it'll hardly ever get used on sidewalks.
How big is this lot? size would dictate how fast you can go. Paved or natural surfaces? condition of surfaces? This imo should dictate what you build for use on the unused lot. Sidewalks would mean it is in an urban area? Paved good condition asphalt Racing gocart. Poor condition asphalt gravel/dirt surfaces require more height suspension different tires.
