Cars are waaaay better than horses. So now we have systems of licensing, proving you are capable of driving safely, ways to track your car ensure it is driven safely - perhaps originally if a police officer saw you and now every minute of the day we can see if you are speeding or potentially dangerous
We did all this over time, but the current system woukd give Sherlock Holmes a heart attack.
But we had to find ways for millions and millions to live on top of each other - it is not perfect and can be improved - and should be done with care.
