Some parking spaces may be designed for bursting loads, and the wires actually do heat up if used continuously. They may still need upgrades for EVs, but overall should be only a modest cost.

When it's -25C outside the wires heating up isn't really an issue, it's more of a bonus feature :D
But yea, the cabling needs to be checked by an actual electrician and they'll determine how many cars can be charged in the ye olde block heater system without melting any wires or tripping fuses.
The 1980's stuff can usually handle 8A continuous loads. They changed the standard some time in the mid 90s, those can handle multiple cars at 10-16A continuous depending on the main fuse.
Anything above that and you'll need to overhaul the whole field and people usually go for Level 2 capable cabling if they need to break ground for cabling anyway.
The power grid hasn't melted even though the plugs at the parking spots are on a timer and usually run two hours from 0600 to 0800 so the car is nice and unfrozen when it's time for the daily commute.
Now when we are moving to PHEVs and EVs some people are _very_ worried that an EV using the exact same plug with the exact same load steadily from evening to morning will melt the entire power grid and the local wires and melt the plug. Dunno why.
Street parking is still an issue, but there are solutions for that too. The power could be pulled from street lamps for example.
