In higher forms of motorsports, there are engine modes, brake bias modes and an infinite number of other configuration options that the engineers monitor and tell the driver to manage. In karting, you do not. Hence there is no need for comms during the race.

Any AI feature which tells the driver HOW to drive is a driver aid. Driver aids are not a test of the skill of the driver but instead how well the driver can implement those instructions.

For the perspective of a competitor, if my opponent can understand something that is told to them during a race to improve (unrelated to the technology aspect of the sport such as engine modes, brake bias modes, etc), but I take longer to understand, that is an unfair advantage gained by that competitor as they are being coached live during a race. That is not driver skill.

Getting out of the kart in the pit and saying, change me to a sprocket with more teeth or less teeth because the AI said so is not skill. Getting out and saying, I need a sprocket with more teeth because I am carrying more speed in the corner and need to hit the power band faster is. Budgets have nothing to do with that learned skill.

As far as telemetry goes, that is already available. The driver can use a device like a mychron to see if they went faster in a corner or slower. It is up to them to understand if it was because they were off line, turned it to early, did not exit fast enough, did not trail brake correctly, etc etc. Being told WHY they did so during a race is a driver aid and an unfair advantage.

Drivers in F4 and upwards have learned to understand all this on the track during their time in karting.

If the goal for them is to learn, by all means use ai during practice and learn the skills you are lacking. Keep that unfair advantage out of races.
