Nissan is testing a Cooperative Adaptive Cruise Control system (CCM) that lets a lead vehicle share real‑time data with following Nissan cars, even when non‑CCM vehicles sit between them. By maintaining a 30‑ to 60‑second gap and smoothing deceleration, the system seeks to curb the stop‑and‑go waves that cause congestion. Senior researcher Jerry Chou describes the approach as “mixed autonomy,” using embedded LTE modems and cloud connectivity rather than DSRC. Simulations suggest noticeable benefits at just 4‑5 percent market penetration, and future plans include driver feedback and potential licensing to other automakers. Read more →

Residents in Los Angeles and Arizona have reported that Waymo robotaxis often idle on residential streets, repeatedly occupying the same curb spaces in front of specific homes or apartment buildings. While Waymo says its vehicles choose parking spots based on local regulations, demand, and energy efficiency, neighbors describe mixed reactions ranging from amusement to annoyance, especially because of the vehicles' constant cameras. The company acknowledges the behavior, notes that vehicles may park on‑street when not heading to a depot, and claims it can mark spots as no‑parking zones in response to complaints. Experts highlight the opacity of machine‑learning decisions behind the parking patterns. Read more →
