Popular councilor Antonio Losa criticized that the measure was implemented «suddenly and immediately and without alternatives for residents», particularly affecting areas where residential parking has been most impacted. Losa recalled that during the PP's term, an expansion to encourage vehicle rotation was studied, but with a different approach than the current one.

According to Losa, any expansion should have been applied progressively, neighborhood by neighborhood, listening to residents and providing specific resources. As an example, he cited the case of El Bulevar, where a potential blue zone expansion should have been linked to the creation of free surface parking on a plot at Federico Mayor Zaragoza street, to address the real needs of the neighborhood's residents.

The popular spokesperson also questioned the awarding of a nearly one-million-euro contract for the purchase of parking meters, considering it «precipitate» as the City Council should still have been in a phase of technical assessment, dialogue, and listening to residents. He also warned that the budget approved for 2026 contemplates doubling revenue from the blue zone, urging that the measure should not be solely for revenue generation but part of an integral plan.

Losa argued that any modification to the blue zone must be accompanied by clear resident discounts, real parking alternatives, progressive implementation, and a global plan considering public transport and park-and-ride facilities. He finally called on the governing team to halt any application that harms residents until «a consensual proposal with the affected neighborhoods exists».
