Wireless Carplay

Hello,
Today I used CarPlay wirelessly for the first time and I noticed a significant issue: VoiceOver audio comes through the car speakers, unlike with a wired connection where it stays on the iPhone. Furthermore, there's a tremendous lag, making it nearly impossible to use.
How can I fix this annoying problem?
In addition, when the screen is off, VoiceOver announces the time every single minute, regardless of the connection type (wired or wireless) or the vehicle. This bug has been present for months now.
I'm currently on iOS 18.5 with an iPhone 13.
