Carpool Deville aims to be the world's fastest hot tub

The world needs crazy inventors with wild dreams. While we might not long for the things that they create, their contraptions certainly make the day a little more enjoyable. Take the Carpool Deville as an example. Nobody (well, almost nobody) is asking for a hot tub fashioned from a 1969 Cadillac that is still drivable. But now that you know that such a beast exists, don't try to tell us you aren't at least intrigued.
The team behind the six-year-long project has a pretty ingenious setup worked out. The Caddy's original 472-cubic-inch (7.7-liter) V8 both provides propulsion and heats the water. The interior is entirely replaced with a watertight, fiberglass tub that includes working jets, and the controls are all done by hand.
As if just building a mobile hot tub isn't enough, the team behind the Carpool Deville plans to take it racing too. Specifically, they intend to go to the Bonneville Salt Flats later this year to make a top speed run while immersed in water at over 100 degrees. They even have a roll cage all set to install to meet the safety requirements there.

Cadillac's semi-autonomous Super Cruise pushed back to 2017

It looks like General Motors is discovering just how difficult it is to bring autonomous vehicle technology fit for public consumption to market. The company has pushed back the launch of its semi-autonomous Super Cruise technology by several months. Originally promised by CEO Mary Barra for a fall 2016 debut, Super Cruise was supposed to be offered first on the new CT6 sedan. Automotive News is reporting that won't be the case, following a statement from GM confirming that the new system would be pushed to sometime in 2017. At the very least, that's a several month delay. GM cited the need to get the system right and keep owners safe, which prevented a firm date for Super Cruise's debut. Product boss Mark Reuss was more blunt, though, telling AN, "It will come out when it is ready." Super Cruise would be one of the earliest examples of driverless tech to be put into public hands, following the introduction of Tesla's semi-autonomous AutoPilot system in 2015. Most other automakers experimenting with the autonomous vehicles don't foresee public sales until early in the next decade, including Toyota, Renault-Nissan, and Volvo. Before Barra suggested a 2016 debut, GM originally aimed to introduce its semi-autonomous system in 2020. Related Video:

Lego's 18.5-inch Ghostbusters Ecto-1 will make you feel like bustin'

If there's something strange in your neighborhood, Lego has something to help you take care of those non-terminal repeating phantasms or class-five full-roaming vapors. This week, it announced a supremely detailed version of the Ecto-1, the iconic 1959 Cadillac Miller-Meteor ambulance from the 1984 film classic, Ghostbusters. The set is comprised of a whopping 2,352 Lego pieces and when completed, will measure 18.5 inches long. It's one of the more accurate Lego vehicles the company has created, and features a steering box connecting the steering wheel to the front wheels, hinged doors and an opening hood with replica V8 engine inside. Like the movie car, it's packed with ghost-fighting gadgetry. There's a rotating ghost-sniffer activated by the wheels, a gunner seat that deploys from one of the rear doors, and a roof rack stacked with loads of spirit-trapping gear. Lego says it's even got some easter eggs that will be discovered as the kit is assembled. Lego says that two automotive pieces were developed specifically for the Ecto-1: a 6x14 curved windscreen and a five-module steering wheel. These should translate well to other vehicles in the future or for custom builds. Notably, this kit was designed by the Michael Psiaki, who created Lego's James Bond Aston Martin DB5 kit. The set is released as a tie-in with the upcoming Ghostbusters: Afterlife movie. It was supposed to be released this summer but was delayed until (as of now) June 2021 as a result of the COVID-19 pandemic. As for the Ecto-1 kit, it will hit shelves Nov. 15 just in time for holiday shopping.
