Are you sure? My state is that e.g. Netflix, Google, Akamai?, etc. offer ISPs to put a (couple of) 2-4U box(es) inside their network, for free, only requiring power and cooling (and networking). The ISP wants this, because he'd otherwise get the traffic dumped into his network at the edge, i.e. an internet exchange/carrier-neutral DC.

That costs the Provider significant routing and intermediate-distance (40~100km, i.e. CWDM long-range transceivers) bandwidth. This is much more expensive then feeding the google box with power.

It is just an infrastructure investment. It's no different from Amazon building a local distribution center in your city.

An "internet fast lane" would be like the city government saying to Amazon, "and also, all traffic lights will immediately switch to green for amazon delivery vehicles."

No, they're still using the same roads as everyone else, they're just starting from a lot closer to the destination.
