So what if it is 60-70 years old? It worked. You didn't want your electric power costs to go up just to replace functioning wires and poles?
You are suffering from The Gasoline Station Delusion. For some reason just because we have a gasoline station (or 4) on every corner you think an EV is not usable unless it too has charging stations equally spaced. The difference is that you have to go somewhere to fill your gas tank every couple days or every couple weeks. But for about $500 you can have a 10kW EVSE at your home which will fill the hungriest Tesla from dead flat to maximum range in 10 hours. 10 hours during the evening and morning when there is a great surplus of electrical power generation, some even offer 50% to 80% discounts for using power during those times.
So, you have an EV that easily drives 150 miles on one charge? When for 30 seconds of effort you could reach to the left for power cable, turn right and insert in car each night, just how often would you pay double the cost to use a public 150kW charging station at which you had to wait 15 minutes? The pathetic charging you see at some restaurants and grocery stores is rarely more than 7kW which takes an hour to put 20 miles of range in my Tesla. That is just fine for charging overnight but not worth the effort at the grocery store. Those are nothing but virtue signaling.
Elon Musk has the EV charging model correct. The proper application for quick charging high power stations is for facilitating travel between cities. Hence initial placements are 100-150 miles apart.
Hotels and homes are a good place for the $500 L2 10kW AC charging stations. Tesla calls "destination charging" and has a program to give away the hardware, even help pay the cost of installation, on the condition that one's customers not be charged for their use or electricity. The hotel can limit use to paying guests but can not charge for the service. Tesla even provides J1772 hardware for non-Teslas.
