Could the new Driver Alcohol Detection System for Safety (DADSS) save 10,000 lives?

The American government has been advising its citizens not to drink and drive for decades, but for the first time, it may be able to physically stop you from getting behind the wheel while hammered. A new system called the Driver Alcohol Detection System for Safety (DADSS) will actually prevent a car from starting if its driver is intoxicated. Last week in Washington, the National Highway Traffic Safety Administration unveiled the revolutionary new technology, which has been the culmination of work and research that has been ongoing since 2008.

Driver Alcohol Detection System for Safety – Technology Overview

So how does it work? DADSS detects alcohol levels by way of two key mechanisms — the first is a breathalyzer system located either on the steering wheel or the driver’s side door that is capable of detecting alcohol in the air particles around it. This means that even if the driver doesn’t have the foresight to blow into the device, or doesn’t want to, the system will still be able to determine how many drinks he or she has imbibed.

The other method involves a touch sensor mounted either on an ignition button or a gear shift that employs near-infrared tissue spectroscopy to determine the driver’s blood alcohol content. Like the breathalyzer system, if it registers over the legal limit of 0.08, the system will disable the care, and driving simply won’t be physically possible. Additional features include programming cars to shut down if the driver is under 21 and has had anything at all to drink.

DADSS is still several years away from being implemented in real cars. While the NHTSA would certainly advocate for automakers to install the technology in their vehicles, it would not be a required feature. The agency hopes that with a successful initial launch, DADSS will eventually become commonplace.

Still, the system has met with some opposition, with skeptics claiming that it will not curb drunk driving as much as it will simply prevent casual drinkers from getting home safely. After all, the American Beverage Institute points out, your BAC level rises over time before eventually dropping, and if a car were to stop operating mid-highway, this could present not only a huge inconvenience, but a risk in and of itself.

But NHTSA head Mark Rosekind remains optimistic. “There is still a great deal of work to do, but support from Congress and the industry has helped us achieve key research and development milestones,” he said. “DADSS has enormous potential to prevent drunk driving in specific populations such as teen drivers and commercial fleets, and making it an option available to vehicle owners would provide a powerful new tool in the battle against drunk driving deaths.”

Should you buy a used EV? Maybe, but it’s complicated

Electric cars are slowly but surely getting cheaper. Over the past year or so, Ford and Tesla have been discounting their most popular electric cars while other brands, like Rivian, are laying the groundwork for all-new cheaper models.

But you'd still be hard-pressed to call electric cars cheap, and buying a completely new car in the first place is a hurdle in and of itself for many potential buyers. According to Statista, used car sales represented around 74% of all car sales in 2022, and while this figure is likely to change as electric cars get cheaper, the fact remains that most car buyers would prefer to save cash and buy used rather than buy something new.
Buying a new car ain't what it used to be
Buying a car with an electric powertrain doesn't necessarily need to be all that different from buying an internal combustion engine (ICE) vehicle. But there's a little more to it than that.

Rivian R2 vs. Ford Mustang Mach-E: Will the R2 be a better buy?
Side of the Rivian R2

The Rivian R2 has finally been announced, and it could end up being the go-to EV for drivers who want a decently affordable electric car with a rugged look and feel. But when it finally launches to the public, it won't be the only option in its price range -- the Ford Mustang Mach-E could be one of its main competitors.

The Mustang Mach-E may not be quite as rugged-feeling as the Rivian R2, but it does have a lot going for it -- like an increasingly low price, sleek design, and comfortable interior. Is one of these EVs better than the other? We put the two head-to-head to find out.
Design
The first thing to note about the two cars is their design, as they’re pretty different. The Rivian R2 is built to be a little more rugged and outdoorsy, while the Mach-E instead has a sleeker and sportier look to it. Both cars look stylish and modern.

2025 Mercedes-Benz EQS sedan gets new face, bigger battery
2025 Mercedes-Benz EQS sedan front-quarter view.

The Mercedes-Benz EQS sedan arrived during the 2022 model year as the flagship of Mercedes' EV fleet. But now that it's been on sale for a few years, it's time for this flagship to get a refit so that it can stay competitive with other six-figure electric sedans like the BMW i7, Lucid Air, and Tesla Model S. The updated EQS sedan is scheduled to reach dealerships later this year as a 2025 model.

One of the most controversial features of the EQS has been its unorthodox streamlined shape, which makes the EQS one of the most aerodynamic sedans around, but also means it doesn't look much like a traditional Mercedes. For 2025, the EQS takes a step closer to that traditional look with a new grille featuring chrome bars like on the Mercedes S-Class. It also sports the brand's trademark hood ornament.
