This is a non-issue. Where I'm from, grid neighbourhoods are the norm and stop signs are not a thing. First, the grid spreads out traffic inside it. Then, you're supposed to drive at around 35 km/h. Last, narrower/streets with more traffic tend to be one way. Most of the driving takes place at arteries, still part of the grid. Those have semaphores.
Also, grids add A TON of public street parking. Get off your arterial road close to your destination and into the neighbourhood and look for parking. That also means there's street and sidewalk space for bus stops and space for laying out utilities (electric, water and sewers).
What I'm trying to say is that grids are meant for cars among all the other things. The thing about non-grids is they are upscale: less public surface means bigger lots and worse transportation means leans non-residents around.
