However, 1972 and 1973 were slow years. Only 7 new models were made in 1972. Of the 24 models appearing for 1973, only 3 were new models. Also the cars changed from Mattel's in house Spectraflame colors to mostly-drab, solid enamel colors, which mainline Hot Wheels cars still use today. Due to low sales, and the fact that the majority of the castings were not re-used in later years, the 1972-3 models are known to be very collectible.
Two other innovations were introduced briefly in Hot Wheels cars in the 1980s - Thermal Color Change paint, and rotating Crash Panel vehicles. The former were able to change color on exposure to hot or cold water, and there were an initial release of 20 different cars, available as sets of three vehicles. The latter were vehicles with a panel that, on contact, would rotate to reveal a flip side which appeared to be heavily dented. Variations in crash-panels included front, rear and side panels, the last of whose mechanism has proven to be the most durable.

As cool as Anki though? Probably not. Hot Wheels is a toy company and actually outsourced the "smarts" of these cars. , and has built a lot more intelligence into its products. There's actually a hidden USB port on the Hot Wheels AI cars, hidden under the plastic chassis, so perhaps more interesting firmware or add-ons are forthcoming. For now, Anki is still the AI leader in the rapidly crowding space of self-driving toy cars.
