2012 Honda Civic handling is bad?

I'm not sure if something is wrong or if it's normal for this car. I primarily drive a 2014 Ford Escape and I know it's a suv but is fairly easy to drive. My mom has a Civic and sometimes we switch cars just because and whenever I drive her car I feel like the car never wants to drive straight and always blows around on the highway. It's the LX model with around 59 thousand miles. Maybe I'm not used to it because I don't drive it often but is that normal for this car? It's fine on the side streets and my mom never drives the highway anyway so it doesent bother her.

Sounds like something is wrong. It should not wander around like that.
Could be tierod ends ball joints etc. How long since its had a front end alignment?
I would start with the alignment and explain what it does. If there's an issue they will find it.

Sounds to me like you need to check all tire pressures and air them up to the recommended pressure listed on the drivers door post. If one tire is low of air the car will wander like you describe.
