Cadillac to launch Super Cruise semi-autonomous technology in two years [w/video]

We all know that self-driving cars are coming. It's not so much a question of If so much as When. And when it comes to General Motors products, we now have something of a date to work with, as Cadillac has announced plans to roll out what it is calling Super Cruise technology in an unnamed new model within the next two years. As you would expect, this new tech can speed the car up, slow it down and keep it in its intended lane, but GM isn't expected to release a fully self-driving car, saying that it will still require "an attentive driver."
We're not quite sure what new model Cadillac will use to launch this new technology, but our best guess would be its upcoming LTS sedan. Other possibilities may include a new crossover - we've heard rumors of CUVS coming from Caddy both above and below the current SRX - or entry-level sedan, but those seem less likely than a high-dollar flagship like the LTS.
The next techy bit of kit currently being shown off by Cadillac engineers includes vehicle-to-vehicle and vehicle-to-infrastructure communication, technology which would seemingly allow cars to travel in close proximity to one another, with less danger of collisions. According to our friends at Engadget, GM is working with the University of Michigan to outfit some 120 miles of roads in and around Detroit, MI, with the requisite sensors to make all this technology possible.

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.

40+ cars that barely avoid the gas guzzler tax

The Gas Guzzler schedule, with mpg ratings and charges that haven't changed since 1991, lays out which fuel-swillers owe what to Uncle Sam.
I started thinking about the "Gas Guzzler Tax" - considerably less well known as The Energy Tax Act of 1978 - when I was driving Dodge's new Challenger SRT Hellcat last week. Unsurprisingly for a car that can burn 1.5 gallons of gas per minute at max tilt, theoretically able to empty a full tank of premium in about 13 minutes, the Hellcat will be subject to the Gas Guzzler Tax schedule when it goes on sale.
