You’re thinking of ACLs and just wearing a brace until you have surgery. You can’t walk after an Achilles rupture because you have no ability to plantarflex your foot. All of your calf muscles become useless because they no longer have an attachment. You wouldn’t be able to do something like pushing on the accelerator or brakes. You’re also non-weight bearing for over a month. I started residency on the neurology consult service on crutches (meaning you’re going around every random place in the hospital all day), which was great. When I ruptured my other one two years later, I got a knee scooter, which was a huge game changer and a world of difference. I have no idea why that hadn’t crossed my mind before and why nobody had recommended it.
