usage
gá is a Wu-dialect (Shanghai-area) reading heard in 轧朋友 (to make friends), 轧闹猛 (to join a lively crowd), and 轧账 (to reconcile accounts). It rarely appears in standard written Mandarin.
车 on the left is the vehicle radical, simplified from 車, a top-down picture of a cart with wheels and axle. It supplies the meaning of 轧 directly: to crush is to roll a heavy wheeled thing over something. Same family: 转 to turn, 输 to transport.
乚 on the right is a variant of 乙, supplying the sound yǐ which shifted to yà. The single curved stroke also reads visually like the long sweep of a wheel pressing down and rolling forward.
