The operators in November came up with a number of suggested improvements, including equipping the scooters with licence plates that would allow easier tracking of riders running a red light, or travelling in pairs on the single-person vehicles -- both common violations.
But David Belliard, Hidalgo's deputy in charge of urban transport, still said a cost-benefit analysis did not favour the rental schemes.
"They are in the way and they are dangerous," he told AFP, saying he favoured a ban to "pacify our streets and pavements".
There was "too much negative feedback" from citizens about the scooters, he said.
Hidalgo told Le Parisien meanwhile that privately owned scooters, also hugely popular in the capital, were not targeted in the referendum. They are "not a problem", she said.
