I’m not facile with google maps but you can see the superchargers here:
supercharge.info
I went from Laredo to Ramos Arizpe then
Matehuala-SLP, San Luis de la Paz-GTO, San Juan del Rio-QRO, Temascalcingo-MEX, Atizapan de Zaragoza-EM, Silao-GUA, Aguascalientes-AGS. I skipped the two chargers around Mexico City after being stopped and had planned not to go to the coastal one due to state department warnings.
Best practice Mexico city: Avoid driving there.
If you have to go to Puebla:
following route:

It's called "Arco Norte" and let's you bypass Mexico City. Heavy toll, but way worth it.
I slept at superchargers at Ramos Arizpe, which was a 24 hour truck stop, coming and going and Temascalcingo, which had a lightning strike power outage that helped me explain to security why I lingered after eating there.
Very, very brave to say the least.
I'd always get a motel with secured parking.
I broke with my plan not to drive at night once in order to get to s SC I felt I could overnight at though I felt pretty safe on the toll roads. The big danger was poor visibility and occasional broken down or unlit vehicles.
The main highways from/to Mexico City at night are not that bad, especially since the really long road traings (doble-semi-remolque) tend to to drive there with 110 kph/70 mph.
Wasn’t too concerned about banditos and heard later that they tend to be less malignant than the cops. I met a guy with a new 3 at the Laredo SC with family in Mexico and he said he wouldn’t drive it down there. I don’t know if a convoy would be safer or just draw unwanted attention.
Sometimes people who live in the states and are visibly Mexican tend to be treated even worse by cops than anyone else, especially if they drive a newer US-plated car.
The first day between Laredo and Ramos Arizpe, I took a Tesla detour due to a crash on the toll road. I probably would have had a much better, false impression of conditions if I hadn’t been exposed to the local roads. Sat through a two hour crash closure the next day so as not to repeat that experience. Toll roads are expensive though absolutely worth it and I’m a major skinflint.
If it was on the stretch Nuevo Laredo-Monterrey: Don't repeat. That toll road is really worth it.
I still don't get it why they are planning to build a supercharger in Salinas Hidalgo.
I’d read of several folks who’ve driven for years and many thousand miles throughout Mexico without incident, so tried to discount knee jerk fear based on anecdotes. Not knowing Spanish was a pretty big disadvantage. I don’t know if there was signage that would have appropriately warmed me not to endeavor into city limits against local ordinances.
I've been living down here for 12 years.
What has changed?
a) general road infrastructure has improved but still far behind anything a westener would call "appropriate". General sense of neglection still very present
b) Traffic density: Up by 30 % min, in certain places up to 40-60 %.
c) more newer compact cars on the road
d) driver's incompetence: Same like before, feels worse due to more cars on the road
e) urban freeways: Huge improvement, but always require attention when driving (potholes in the middle of nowhere etc).
f) all in all, you get by way better with a laid back attitude in driving. And I really mean laid back. Red lights though are generally respected.
g) signage: Useless, often misleading or plain wrong. Plan EVERY trip ahead with google maps/street view (works in MX, has saved me numerous times)
h) in big cities: Use uber. Really a blast
