In my opinion, this is the worst attraction at the Magic Kingdom. I get that kids like to drive cars, and that it doesn't matter much if a gown adult like me likes this attraction. That being said, Disneyland's Autopia has far more features, which makes their version almost exciting.
I'm sure Tomorrowland Speedway will be on the chopping block someday soon as it neither fits Tomorrowland theming nor are the cars speedy... and that this attraction takes up more space than the Rivers of America and Tom Sawyers Island combined. There is just nothing futuristic about ICE cars, particularly the model cars used. For the speed they go, the stench of hydrocarbons is impressive. Kids who didn't grow up with actual cars smelling like this will get a nice glimpse into the distant past.
If kids continue to get a kick out of it, I would think an electric car manufacturer could be convinced to sponsor a faster electric version, possibly even trackless with lidar safety features, which at least would bring Tomorrowland Speedway up to the present. Until that happens, it wouldn't hurt to make the track exiting and the ride entrance less like something that rolled off a truck at a county faire.
