Without some system to manage charging times, there will be fun times when enough houses on a pole transformer start charging simultaneously and blow out the transformer.

How would it be any different if everybody on the block started their dryer at the same time? Also, the x-former "on the pole" only feeds on residence. If you are talking about a substation that's different but still it's no different than the dryer hypothetical.

The situation is different. Dryers operate for shorter periods at various times of day. There is no reason to run dryers for long periods during the same window of non peak hours. Because of the charging time required, EV owners will charge during the same window of non peak hours.
