Originally built in Disneyland at a time when freeways were considered tech breakthroughs and not a bane of life, this half-mile, self-driven jog of four-lane track is the first chance most kids will have to drive. These are go-karts with no juice, although the late sportscaster Tom Carnegie—known as the Voice of the Speedway—calls the “race” and the gas-fired engines reek and snarl. Each vehicle carries two people, steers poorly but is guided by a rail, and won’t go fast (about 7mph) no matter how much pedal meets metal. Though the queue can be blistering hot and the load process tedious, your puttering will end in about 5 minutes. Strategy: Mind the height restrictions—kids shorter than 54 inches can’t go alone, a rule that sparks tantrums.
