Any electric car that uses batteries needs a charging system to recharge the batteries. The charging system has two goals: To pump electricity into the batteries as quickly as the batteries will allow. To monitor the batteries and avoid damaging them during the charging process.
A filibuster is a parliamentary procedure where debate over a proposed piece of legislation is extended, allowing one or more members to delay or entirely prevent a vote on the proposal.
Of course, the filibuster is by definition a tool for a Senate minority to obstruct a Senate majority. But since Rhode Island and California enjoy equal representation in the Senate, a majority of senators isn't the same as a majority of Americans.
