More than 100 pink Cadillacs assemble for Aretha Franklin’s funeral today

Aretha Franklin's funeral service is under way today in Detroit, and plans call for a service of at least five hours featuring performances by stars including Stevie Wonder, Ariana Grande and Chaka Khan, speakers including former President Bill Clinton and the Rev. Al Sharpton, and at least 130 pink Cadillacs lining the road in front of the church. The gesture is a nod to Franklin's Grammy award-winning 1985 hit "Freeway of Love" and its lyrics about driving in a pink Cadillac. Crisette Ellis, the wife of Bishop Charles Ellis III of Detroit's Greater Grace Temple, said they were inspired by how police line up their cars during funerals for fallen officers. "My husband said, 'Wouldn't it be awesome if we could have a sea of pink Cadillacs parked on Seven Mile Road to greet Ms. Aretha Franklin as she arrives?'" she told NPR.

"They're coming from everywhere," she said. "They are coming from as far as Texas; Omaha, Nebraska; Florida; North Carolina; Maryland." The funeral, which officially kicked off at 10 a.m. EST at Greater Grace, caps a weeklong celebration of Franklin's life and songs, including a two-day visitation at the Charles H. Wright Museum of African American History and concerts. Performers also include Faith Hill, Jennifer Hudson and the Clark Sisters, while Tyler Perry and the Rev. Jesse Jackson are also scheduled to speak. HLN and the Word Network, plus several local Detroit television affiliates, plan to broadcast the funeral, and outlets including The Associated Press and USA Today plan to livestream it. Having sung at the inaugurations of three presidents — Jimmy Carter, Bill Clinton and Barack Obama — Franklin was an American institution. She was awarded the Presidential Medal of Freedom by then President George W. Bush in 2005. Clinton entered the church with his wife, Hillary, to loud applause and stood quietly by Franklin's open casket before the service started. Franklin's body was dressed in a golden sequined outfit. The funeral was closed to the public, but crowds of fans gathered outside, many dressed in their church best.

Super Cruise’s failsafes

Even though Super Cruise is not a fully autonomous system, it incorporates redundancies like those used in aircraft to ensure failsafe operation. Before taking off on a 700-mile, 11-hour test drive of the system — and putting my life in its hands without my hands on the wheel — I sat down with Daryl Wilson, lead development engineer for Super Cruise, to get a deep dive into the system and its critical safety backups. Autoblog: First, what makes Super Cruise different from similar systems? Wilson: The key differentiator for Super Cruise is hand-free driving. It's an industry first in that respect. Our competitors require the driver at minimum to place their hands on the wheel with some frequency to ensure that the car knows that the driver is there. We don't. Two key technologies allow us to do this. One is our Driver Attention System, which is our methodology for making sure the driver is engaged with the vehicle and engaged with the road. This is a driver assist system, not a fully autonomous system. So it requires driver engagement. We use an infrared camera that constantly monitors the driver's face to determine the direction they're looking. We're looking for the driver to be what we call on-road — not on the center stack, not to left or right or down. That's all done by the tracking of the face. We also track that the eyes are open. It's infrared because at night you need to illuminate the face and you can't be shining a light into the driver's face. Then we have our lidar mapping that provides a foundation for control and redundancy to ensure safe performance. Autoblog: How does the mapping act as a redundant feature? Wilson: This system is only for use on divided, controlled access highways. What I mean by a divided highway is something more than a painted line between you and oncoming traffic. Whether that's a grassy area in between the lanes or a concrete barrier, anything that separates you from oncoming traffic. That's the divided highway part. The controlled access part is entrance ramps and exit ramps. Not with roads that cross at grade, with traffic crossing at the same level. To do that we geofenced these roads to ensure that operation is only allowed in these conditions. We don't just recommend you use it there; we ensure that you only use it there.

GM Ultium tech can scavenge heat from everywhere, even you

GM likes to give us tidbits about its Ultium platform from time to time, and today it’s telling us about the platformÂ’s ability to capture waste heat from the propulsion system. In addition to capturing from the propulsion system, it can also capture humidity from both inside and outside the vehicle and even from passengersÂ’ body heat. Yes, you, your family and/or your friends are a usable heat source as far as GM EVs are concerned. It then deploys the heat in an advantageous way. If at this point, youÂ’re screaming, "Heat pump!" youÂ’d be right. WeÂ’re talking about an elaborate heat pump system that GM is using for its Ultium-based vehicles. Every Ultium-based GM vehicle gets this system that is covered by 11 patents and four publications. The waste heat it collects is used in a number of ways, but its primary use is to heat the cabin quickly and efficiently. GM claims it can heat the cabin of its Ultium-based vehicles quicker than vehicles with traditional internal combustion engines. Plus, when put to use, GM claims that using the heat pump provides its EVs with up to 10% more range than theyÂ’d have without. Beyond heating the cabin, the heat pump is capable of putting waste heat to use by preheating the battery prior to charging so that you can charge quicker. The system can even cool the propulsion system in preparation for Watts to Freedom (WTF) launch control starts. GM says this was vital in helping the Hummer EV achieve its bonkers 0-60 mph time of about 3 seconds. “Having a ground-up EV architecture gives us the freedom to build in standard features like UltiumÂ’s energy recovery capabilities,” said Doug Parks, GM executive VP of global product development, purchasing and supply chain. “This helps us squeeze more efficiency, performance and overall customer benefit out of our EVs.” GM says itÂ’s been developing heat pump technology since the EV1 and its heat pump. This is the modern evolution of that technology, and GM says itÂ’s going to be implemented in every Ultium-based vehicle as a standard feature.
