Of course, it's different if you're constantly doing 1RMs, but I doubt your workout consists solely of that.
Off the top of my head I can't think of any other major exercises that require a spotter. Squats maybe? But for those you can just use a smith machine.
I used to only go to the gym when I had a friend to go with (this was back in college so it wasn't a huge pain). Starting to go by myself was the best change I ever made. Not being beholden to another's schedule for your own wellbeing is a glorious thing indeed.
With a smith machine, you don't get the full range of motion you have with real barbell squats - it's straight-line up and down. I also am not a fan of the twisting motion you need to perform to get the bar locked in.
Have also done a good amount of biking but haven't lived in an area that's safe for it in a while.
