Will Level 2 Connected AV Tech Be Ready by 2028?

 

The trajectory of autonomous vehicle (AV) technology is often framed as a race toward a driverless future (Levels 4 and 5). However, the real immediate battleground for mass adoption lies in Level 2 (L2) Partial Automation paired with Connected Vehicle (V2X) technology.

 

As we look toward 2028, the question isn't whether L2 systems will exist—they are already on the road today. The true question is whether connected L2 technology will achieve the systemic maturity, regulatory approval, and infrastructure integration required for a seamless, synchronized driving experience.

​

The Core Concept: What is L2 Connected Tech?

First, it's important to make the distinction between two fundamentally different automotive technologies:

• Level 2 Automation: Systems that handle simultaneous steering, acceleration, and braking (e.g., Tesla Autopilot, GM Super Cruise), but strictly require the human driver to remain fully attentive.

• What it isn't: Level 3+. Vehicle-to-Everything communication, allowing cars to "talk" to other vehicles (V2V) in real-time, relying on both its own eyes (cameras, radar, LiDAR); it relies on a shared, collective network intelligence.

​

Why 2028 will be the Critical Tipping Point:

The trajectory of autonomous vehicle (AV) technology is often framed as a race toward a driverless future (Levels 3 and 4), but the real immediate battleground for mass adoption lies in Level 2 (L2) Partial Automation paired with Connected Vehicle (V2X) technology.

​

As we look toward 2028, the question isn't whether Level 2 systems will exist—they are already on the road today. The true question is when connected Level 2 technology will achieve a unified standard, regulatory approval, and the sufficient bandwidth required for a seamless, safe, and synchronized commute.

1. Growing Marketshare

​More than half of new vehicles sold in the US in 2024 had Level 2 autonomy. Unlike existing freeways and existing roads, elevated autonomous routes do not need ubiquitiuos conversion to deliver transformative traffic volume. The existing US fleet is rapidly approaching enough marketshare of the existing fleet having Level 2+ autonomy for sufficient demand to make building connected, elevated routes profitable. Th

 

2. L2 Digital Toll Gantries Prevent Bottlenecks

Level 2 autonomous vehicles are capable of being guided with toll gantries that signal to vehicles when to speed up and slow down in ways that are coordinated with other traffic flows. While OEMs and regulators have not yet agreed to a standard, they are expected to do so sooner than later. Existing Level 2 autonomous vehicles are expected to be compatible with any such standard, and will soon be the majority of existing vehicles on the road.

3. Resolving the 5.9 GHz Spectrum Debates

For years, V2X deployment was stalled by regulatory debates over the 5.9 GHz cellular band. With the industry firmly converging on C-V2X (Cellular Vehicle-to-Everything) protocols, the runway is clear.​
