Federal authorities have finalized their inquiry into Tesla's Smart Summon feature, a system enabling remote vehicle parking, after the company implemented software modifications addressing reported minor collisions. This resolution, while positive for Tesla, occurs as a broader investigation into its Full Self-Driving (FSD) capabilities continues, highlighting the ongoing regulatory examination of autonomous vehicle technologies.

Federal Regulators Close Smart Summon Investigation Following Tesla's Software Fixes

On April 7, 2026, the National Highway Traffic Safety Administration (NHTSA) formally concluded its investigation, labeled PE24033, into Tesla's Smart Summon feature. This decision came after Tesla introduced several over-the-air software updates aimed at resolving issues identified in reports of minor, low-speed incidents. The probe, which began in early 2025, focused on the system's performance in environments like parking lots, where vehicles, when operated remotely via a smartphone, occasionally made contact with static objects such as parking gates, bollards, or adjacent cars.

A comprehensive review of 159 reported incidents, including 97 classified as crashes, revealed no instances of injuries, fatalities, or involvement of pedestrians or cyclists. The core problems identified included challenges with user visibility through the application, limitations when cameras were obscured by conditions like snow, and the system's occasional inadequate response to moving obstacles. Furthermore, some incidents were attributed to drivers failing to intervene promptly despite on-screen warnings. The NHTSA's closure of this specific case acknowledges the effectiveness of Tesla's software updates in mitigating these concerns. However, the agency emphasized that this closure does not constitute an endorsement of the system's absolute perfection. Crucially, the larger and more extensive investigation into Tesla's Full Self-Driving system remains active, indicating that regulatory oversight of Tesla's advanced driver-assistance technologies is far from over.

The conclusion of the Smart Summon investigation offers a moment of relief for Tesla, demonstrating that targeted software enhancements can address specific regulatory concerns. This event underscores the dynamic nature of automotive technology and regulation, where continuous innovation is met with evolving safety standards. For consumers, it reinforces the importance of ongoing vigilance and understanding the limitations of semi-autonomous features, even as manufacturers strive for greater technological sophistication. The ongoing FSD probe suggests that the path to fully autonomous vehicles remains a complex journey, requiring meticulous development, rigorous testing, and transparent collaboration between innovators and regulators to ensure safety and public trust.

Colorado has implemented a pioneering automated speed enforcement initiative along a segment of I-25. This system distinguishes itself by calculating a vehicle's average speed across a defined distance, rather than capturing a single moment's velocity. This strategic deployment targets high-risk zones, such as active construction sites, where traditional speed monitoring methods are often impractical and unsafe for both drivers and personnel. The program, which has already demonstrated a significant reduction in speeding violations during its warning phase, levies a civil penalty of $75 on offenders, prioritizing deterrence over punitive license actions. However, a notable loophole exists for vehicles operating without visible license plates.

Since 2023, the Colorado Department of Transportation (CDOT) has possessed the authority to deploy speed cameras in designated high-risk corridors prone to excessive speeding, especially within work zones. The Colorado Speed Enforcement Program previously saw successful application on Colorado Highway 119, between Boulder and Longmont, during construction periods. Its current expansion now includes a five-mile stretch of I-25 south of Fort Collins, approximately 35 miles north of Denver, where crews are engaged in adding new express lanes.

Operating at high speeds within construction zones presents considerable hazards to motorists and workers alike, as well as to law enforcement officials. Employing automated detection mechanisms offers a safer and more efficient alternative to conventional patrolling in these challenging environments, which are often characterized by constricted lanes and minimal or absent usable shoulders.

The enforcement phase for this five-mile corridor officially commenced on April 2. This followed a 30-day grace period during which initial violators received cautionary notices but no monetary penalties. Remarkably, prior to the imposition of fines, CDOT observed a substantial 90 percent decrease in excessive speeding within the designated zone, underscoring the immediate impact of the automated system.

Unlike radar-based devices that capture instantaneous speed, this innovative system utilizes pairs of automated vehicle identification cameras positioned at a fixed interval. These cameras photograph vehicle license plates at both entry and exit points. The system then computes the average speed over the known distance, utilizing the elapsed time between the two photographic captures.

Should a vehicle's calculated average speed exceed the posted limit, a civil penalty notice for $75 is dispatched to the registered address of the vehicle's owner. It is understood that a tolerance of up to 10 mph over the limit may be applied. Importantly, as the system does not identify the driver, no points are assessed against the owner's or driver's license. CDOT indicates that the majority of the revenue generated from these fines is reinvested directly into sustaining and expanding the Speed Enforcement Program.

The locations of these cameras are clearly marked, with advance warning signs placed at least 300 feet before the enforcement zone. For those who may initially exceed the speed limit when passing the first camera, there remains an opportunity to avoid a fine. By reducing speed sufficiently before reaching the subsequent camera, drivers can lower their average speed to within legal limits.

A critical challenge for this system arises with vehicles that lack license plates or are unregistered, a problem already prevalent in Colorado. Similar issues have been encountered with license-plate readers used for enforcing express-lane tolls. This scenario creates a potential loophole for evasion, and authorities are currently exploring how to address this specific enforcement gap.

This pioneering deployment of average speed cameras on I-25 represents a significant advancement in traffic management and safety. By focusing on sustained speed over a distance, the system effectively discourages drivers from momentarily slowing down only when approaching a visible camera. While the $75 civil penalty aims to deter reckless driving without burdening drivers with license points, the ongoing issue of unregistered or plateless vehicles highlights a frontier in enforcement that requires further attention to ensure the program's comprehensive effectiveness.
