I would be possible if you take the innards out of a Scalextric Spark Plug and use it as a digital chip on a digital track - you will get control of power and brakes (and matching sound effects), but no lane changing. And you’d need to use the Spark Plug app on a smart device as the controller.

Five engine sounds are offered:

• V8
  
• Rotary
  
• Motorbike
  
• Monster Truck
  
• Formula One
  

Haven’t done it yet, but it looks very possible. As it is, the sound from the Spark Plug dongle sounds weedy when fixed to the powerbase, but in a nice roomy car body, it should sound quite nice with the sounds coming out of the car.
