10^27. Is your Google broken?

Right up until you were "detained" indefinitely (at what I'm sure would be a first-class Chinese prison) for "suspicious activity".

No. Why would we?

One of the key components to any fire department is mutual aid - we help each other out. We do similar things with external entities. I need high voltage cut off? I call the power company. I know of no specialized "high voltage" unit or response team in any FD anywhere in the world, save for some industrial fire departments working at large power generation facilities.

We will strip a meter out of a box as a last resort, but we prefer letting the power company handle it. They're trained for it, they have the equipment (which they know how to inspect properly), etc. If we have an electrical hazard, we make a risk/reward decision and try to work around it. If the structure is fully involved and we either know everyone has been evacuated (per the homeowner) or we see that the conditions are not compatible with life, then we won't take a big chance. If we know there are three kids trapped in a bedroom, we'll work around the hazard as best we can to effect the rescue. Firefighting is a series of these decisions - is the amount of potential "good" worth a given amount of peril to my life and the lives of my crew?

Now, think about a crunched-up car, especially a little microbox like a Prius. The guys who work on HV for a living don't have "suits" - they have proper clothing, long insulating gloves, insulating boots, etc., along with tools that do their best to keep them away from the high voltage where possible. Ever tried a set of lineman's gloves on? You can forget any fine motor control. Now, think about what happens when you have no fine motor control and you need to mount an effective rescue on a car that's been crunched badly, while people sit inside bleeding to death. As it is, we are issued additional equipment for vehicle extrication and wildland firefighting (dual certified gear) - jumpsuit, gloves, lightweight helmet. The typical structural firefighting PPE is simply too big and bulky, and it impairs movement to the point that working with hand tools, rescue tools, etc. becomes very difficult. Lineman's gear would be even more of a problem.

Plus, how much gear do you carry? As it is, for my personal gear (this is what's in my locker, not counting what lives on the apparatus), I have:
Full set of structural PPE (coat, pants, suspenders, boots, helmet with light/band/wedges, 2 pairs of gloves, medical gloves, hand tools, rope bag, search loop, additional flashlight, etc.)
Full set of extrication/wildland PPE (jumpsuit, gloves, helmet, hand tools, flashlight, medical gloves, rope bag)
Handheld radio, another flashlight or two, more tools, etc.

I carry all of this every time we get a call (about 700 calls a year, I average 50-60%, all volunteer). Add too much more and we'll need a second truck to carry all of the gear!

It's frightening that someone modded you insightful.

Vehicle extrications are death-traps for firefighters. Just to name a few issues:
Shocks in bumpers, prone to send the bumper flying off the car at knee height
Rollover bars, prone to release at the wrong time and pummel anything in its path (already killed more than one FF)
Chemical airbags, which can cause injury or burns
Stored-gas airbags and their cylinders and tubing - not good to cut into a ~3Kpsi cylinder
High-voltage cables in hybrids
Magnesium and springs in steering columns
Hood and tailgate struts, prone to overheating and exploding
Fuel tank, fuel lines, etc.
And more...

Our bunker gear is insulating... from HEAT, not electricity. I carry a few different types of gloves (structural, extrication, work gloves for hose rolling) - none of them are rubber or insulating from electricity either. There is nothing in a firefighter's typical equipment that will provide any significant protection from electricity. Cutting a high-voltage cable in a hybrid will result in significant injury at best... death at worst.
