"Stop-and-go traffic on highways" is quite a narrow usage scenario, isn't it? At least in a lot of highway driving in UK, FR, DE, CH, I find this mostly only happens with major events or roadworks, and even then it's for a short time or distance. The rest of the time you'll be plodding along at 60 km/h, with all other traffic overtaking you, which itself adds risk.
