I agree, but i'm not in charge.
@Marni1971 has said there's at least plans for electric cars, but the ride as a whole simply needs to go. It eats up prime land where they could put multiple attraction or one really nice E-ticket. Over time it will happen, but with Tron being built now, another big build in TL probably won't happen for quite a bit. Adventureland could really use a modern E-ticket.
Funny thing is, when Autopia was designed, the idea behind it is that it WAS futuristic at the time because in 1955, highways weren't a thing. TDL got rid of their Speedway and Disneyland is eventually going to need the land. It's just a matter of when the park needs the land for something actually good.
