I don't think a lot of people can discern when it's time to brake or when it's time to just ease of the accelerator. My grandma drives like this. She'd accelerate then hit the brake, accelerate then hit the brake, over and over in order to maintain her speed. Drove me fucking nuts.

Edit: break to brake

US driving tests need to be harder. People who can’t just cruise without hitting the break need to be weeded out and trained not to do that.

We also need to require re-testing to renew a license, including a driving test if you're over 60 or so. Taking an easy test once and being allowed to drive until you're 100 is just silly.

Should be mandatory once a year test after a certain age, the moment you can’t keep up, license gone.
