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.

2020 Cadillac CT4 First Drive | Small shoes to fill

Following an existential crisis of fits, starts, headquarters moves and executive shakeups, Cadillac has itself a new luxury sedan, the CT4. It’s a convincing driverÂ’s car, less convincing as a luxury car, and seems a long shot to lure BMW, Audi or Mercedes owners into the Cadillac fold. For all the changes at Cadillac, that sure sounds familiar. The 2020 Cadillac CT4 is a redesigned ATS by another, equally unmemorable name. That includes an updated rear-drive chassis with eager, enthusiast-friendly tuning and 50/50 weight distribution – always among the ATSÂ’ top selling points. Styling is another winner, with crisp sheetmetal and CadillacÂ’s distinctive lighting signatures helping to differentiate this Yank from the international crowd. Cadillac is stretching so hard to cherry-pick the CT4Â’s competitors, it's possible they might slip a disc. We all remember the ATS as an able, rear-driven rival to the compact BMW 3 Series, Mercedes C-Class et al. But to paint the CT4 in a more competitive light – even as this sedan grows nearly 5 inches in length versus the ATS – Cadillac suddenly claims that its entry-level model, regardless of what it's now called, competes against subcompact, front-drive-based models like the BMW 2 Series Gran Coupe, Mercedes CLA-Class and Audi A3. Unfurling a tape measure reveals the truth: At a bit over 187 inches, the CT4 is actually longer than a 3 Series, C-Class, Audi A4 and every other major compact player. ItÂ’s a foot longer than an Audi A3. So, it's not a subcompact sedan, but there is one area where the CT4 does align with them – just not in a good way. The back seat is scrawny and hard-to-access, the result of its rear-wheel-drive platform and the sort of inefficient packaging that plagued the ATS. As such, it's better to think of the CT4, like the Genesis G70, as an affordable alternative to the roomier 3 Series, and other German compacts. And thereÂ’s nothing wrong with that. It starts at $33,990, undercutting the Germans by many thousands, and still boasts CadillacÂ’s greatest competitive strength: Smartly engineered ride-and-handling that matches up against the Euros with no excuses required. I drove the evident smart play in the CT4 lineup, the Premium Luxury 2.7 model, priced from $40,990, or $42,990 for the all-wheel-drive version I tested. (A Premium Luxury with the 237-horsepower 2.0T starts from $38,490, or $41,690 with AWD).
