What does it mean when a guy says get home safe?

He texted me to come to the gym because no one else was booked in

we’ve kind of built a friendship

his friend who I don’t know her followed me on instagram so he is obviously talking about me In some form

He told me to get home safe

do guys say that if they care about someone or they are friends with?
