The number of shootings on U.S. interstates is up across the country and a big reason for this is aggressive driving. 

Even with more attention coming to this issue, it isn’t an easy fix according to the police.  

"You have the recipe for some real, real challenges," said Chris Loftis with Washington State Patrol. 

Washington State Patrol is seeing more shootings on highways - and they’re hard to prevent.

"Highways are dangerous enough without anything like this," Loftis said. "It makes it tougher to patrol and respond. And then it makes it tougher to investigate."

 Law enforcement attribute many of these shootings to aggressive driving and the reaction from surrounding drivers. 

"When you have situations where peoples’ behavior is changing about how they’re operating their vehicles," Loftis said. "And then peoples’ behavior changing in how they respond to aggressiveness. You overlay that with more people, more cars."

Over the last year, areas in Washington State, California, Wisconsin, Indiana, Pennsylvania and Florida have reported an increase in highway shootings. 

"The numbers are just too high," said David Reich with the National Road Safety Foundation.   

The best advice for drivers is to try to drive carefully and avoid aggressive drivers.

"Any time, if someone is driving aggressively, just try to stay away from them," Reich said. "It’s human nature to want to curse the guy out or do something to retaliate. But it’s not worth it." 

Washington State Patrol is fighting back with more officers on the road.  

"We’ve definitely put in more emphasis patrols and focused patrol units in certain parts," Loftis said. "Especially since we’re seeing so much."  

A shortage of police officers has also made it tougher to crack down on these shootings.

"Real Time" host Bill Maher closed his show Friday night by urging President Biden to "lean into" his age and "let his old fart flag fly."

"If Democrats want to win the next presidential election, they need to find a way to make the Biden age issue work for them. Because you know what's really getting old about Joe Biden? Complaining about his age," Maher began his monologue about the 81-year-old president. 

"Instead of trying to refute all the ‘too old to be president’ slams, Joe must embrace them. Stop with the 'I'm sharper than ever.' Nobody's buying that. Don't try to deny the age thing, lean into it. Lean in, lean in like you're eating soup," Maher quipped. "And just admit it! Say ‘Yes, I’m bad with names and I walk like a toddler with full diaper, but I believe in democracy."

The HBO host said Democratic candidates have become "defensive" on who they really are, citing John Kerry's duck hunting and Hillary Clinton carrying hot sauce in her purse during their presidential bids, insisting "Americans hate that s---."

"Be yourself! And Joe, yourself is old," Maher told Biden before suggesting he "take a page" from the playbook of his "old pal" John McCain, who embraced his age during the 2008 presidential election.

"No one cares if you can ride a bike and trying to do stuff like that is only setting yourself up for failure," Maher said while showing a photo of Biden when he fell off his bike. "You recently joined TikTok to win over the kids, get off that s--- right now! It's inauthentic and it won't work! You're not following the demographics. In 2020, a record number of eligible voters under 24 came out – as gay! But came out to vote? Not so much. Less than half. But almost 72% of people over 65 voted. Those are your people, Joe. That ‘Matlock’ crowd. Reach out to them… Take all your ads of Twitter and put them on CBS. Tell America I feel your joint pain."

"When the president delivers the State of the Union, I say he should old fart flag fly," Maher added.

Maher went on to demonstrate how Biden's State of the Union address "should" look like, which included using a walker and unabashedly making gaffe after gaffe.

While Maher has long defended Biden against his "agist" critics, he has also repeatedly called him "Ruth Bader Biden," comparing him to the late Justice Ruth Bader Ginsburg, who famously chose not to step down under President Obama and allowed President Trump to appoint her replacement following her passing in 2020. 

He most recently invoked the Ginbsurg comparison following the release of Special Counsel Robert Hur's report, which put a spotlight on Biden's mental acuity. 

"I said he was going to be the Ruth Bader Ginsburg of presidential politics… He stayed too long at the fair," Maher said last month. "Bubbling up this week… he won't do the Super Bowl interview, which is not a hard one, mixing up all the world leaders and then this report that came out."

Biden's age and mental acuity continues to be a major issue for him going into the presidential election as the vast majority of Americans, including Democrats, believe he's too old to seek a second term.
