From Transport Evolved.

Thinking about adding semi-autonomous driving to your EV? Both Nikki and Kate’s families have Comma systems—Kate has one in her 2019 Kia Niro, and Nikki’s wife has one in her 2017 Chevrolet Bolt EV Premiere. So far, they’ve been smooth… except for Kate’s pesky broken USB port.

At Comma Con 2025, the company unveiled the all-new Comma 4, a next-gen eGPU, and teased some exciting future updates. But here’s the question: is upgrading to a Comma 4 worth it? And what if you’re new to add-on self-driving tech?

Nikki takes a spin in her wife’s Bolt EV to test things out and shares her thoughts—pros, cons, and everything in between.
