Weekly Recap: Revisting the BBC report that ended Jeremy Clarkson's Top Gear run

Jeremy Clarkson's long run as a Top Gear host has come to an end, and the reason is clear: His physical assault on one of the show's producers crossed a line, and the government-owned BBC couldn't tolerate it. The incident between Clarkson and Top Gear producer Oisin Tymon was initially described as a "fracas," and Clarkson was suspended. But his popularity and widespread support – even British Prime Minister David Cameron weighed in – suggested that the controversial Clarkson might be given yet another chance. The BBC put this to rest Wednesday when it sacked Clarkson and revealed the findings of its investigation. The report spelled out how Clarkson struck Tymon on the patio of a North Yorkshire (UK) hotel, leaving him with a bloodied, swollen lip. It was severe enough that the producer sought medical treatment. During and after the attack, Clarkson shouted expletives at Tymon and threatened to fire him. The noise carried into the hotel's dining room and even to a bedroom. Local police investigated the incident, but Tymon isn't pressing charges. The huge audience numbers, Clarkson's popularity and the high-octane excitement of Top Gear all melted away in the eyes of BBC director-general Tony Hall, who saw an attacker and a victim. "For me a line has been crossed," he said in a statement. "There cannot be one rule for one and one rule for another dictated by either rank, or public relations and commercial considerations." In that moment, Clarkson was the bad guy, though he was actually the one who reported it to the network and made repeated attempts to apologize to Tymon. He's also urged the media to leave the producer alone. Hall voiced regret in the statement that announced Clarkson's contract would not be renewed, but the BBC decided to move on. Rumors are swirling about possible replacements for Clarkson. The network says it wants to continue Top Gear in 2016 and is looking to air the rest of this season's episodes. Despite the controversy, the show has a global audience of 350 million viewers and is one of the BBC's most valuable properties. It's unclear what Clarkson's co-hosts, James May and Richard Hammond, will do, as their contracts were also reportedly up to be renewed.

How GM engineers are using diaper 'snow' to keep you warm

Testing how snow affects General Motors' vehicles isn't really a problem right now for the company's engineers, but in the dog days of summer the process isn't exactly easy. The only real option is for them to book time at the automaker's climatic wind tunnel. However, a flash of brilliance from an engineer allows snow to be simulated regardless of the temperature outside, and the discovery is all because of his daughter's wet diaper. The realization came to GM Thermal Systems engineer Nicholas Jahn while he was swimming with his daughter and noticed how her diaper ballooned in size in the water. He found out the substance that makes this possible is called sodium polyacrylate. When the material gets wet it grows and forms fluffy flakes that are a close imitation of snow. Best of all, the stuff can be prepared easily any time of the year, and it's reusable. The engineering team uses the material to test the effectiveness of the heating systems of GM's vehicles. They spread the sodium polyacrylate over the inlets at the base of the windshield to obstruct the airflow and then crank the heater. After some time, they can see how much is being sucked into the system and design more efficient systems in the future. See how the process works in the video above and read about the diaper discovery in GM's press release below. Diapers Change Chevy Cruze Winter Warm-up Time GM validation engineer uses diaper material "snow" to reduce frigid drives 2015-01-06 DETROIT – An item commonly found on an infant's changing table is helping General Motors' engineers simulate snow year round, ensuring heating systems in cars like the 2015 Chevrolet Cruze can quickly and efficiently warm its interior. Packed snow can prevent air from entering the inlet panel at the bottom of the windshield, obstructing the flow of air into the heating system and reducing the amount of air it can push out. This can lead to less efficient warming of the car's interior and windshield defrosting. "The last thing anyone wants to do when it's freezing cold out is scrape their windshield," said Nicholas Jahn, GM Vehicle Thermal Systems engineer. "The testing we perform on the Chevrolet Cruze with the diaper material allows us to maximize the car's heating capabilities." Ironically, Jahn stumbled upon his diaper-based testing method in the middle of summer. During a swim with his daughter, he noticed her diaper multiplied in size when it came into contact with water.

Car owners getting more irritated with their repair experiences, study says

The J.D. Power U.S. Customer Service Index Study (CSI) is a barometer of a vehicle owner's happiness with the service experience. While it wasn't all bad in the 2023 study, the overall owner satisfaction score dropped. This year's tally of 846 out of 1,000 is two points down from 2022, the 43-year-old study's first decline in more than 28 years, and one point down from 2021. However, the overall score remains well up from the pre-pandemic scores of 821 in 2018 and 837 in 2020. The study claims the stumbling block is the horde of BEV launches. The flood into the new energy space has created a recall rate among EVs that's more than double the rate for ICE vehicles. Furthermore, dealership service department knowledge of EVs isn't on par with internal combustion engine expertise, leaving EV owners less satisfied with service advisors compared to ICE owners. Chris Sutton, VP of automotive retail at J.D. Power, said, "As training programs for service advisors and technicians evolve, EV service quality and customer experience must address both the vehicle and the unique customer needs. The EV segment has the potential to spur massive convenience improvements in how customers service their vehicles — but weÂ’re not seeing the benefits yet." Matters are slightly worse for all owners, though, with labor and parts shortages contributing to longer wait times for service appointments. The CSI study surveys owners and lessees of one- to three-year-old vehicles to gauge their happiness with service at franchised dealer or aftermarket service facilities for maintenance or repair work. The criteria in order of importance are service quality (32%); service advisor (19%); vehicle pick-up (19%); service facility (15%); and service initiation (15%). Lexus retains the top spot for luxury brands, giving it three wins in four years. The Japanese automaker won in 2020 as well, its run interrupted by Porsche in 2021. Cadillac, Infiniti and Acura complete the luxury top 5.  For mass-market cars, Mitsubishi wins again after a victory in 2021 and falling to fourth last year. It's followed by Mazda, Buick, Subaru and Mini.  Considering the different service needs and service experience of different body styles, the study has broken results out by segment for the first time. Lexus earned a second victory thanks to winning the premium SUV segment, and Mitsubishi earned a second victory by winning the mass-market SUV/minivan category.
