What type of car racing are available (for normal mortals) in the US?
The SCCA defined several types of racing, open to the “public”: Solo I is a high speed event, using cars prepared to road racing safety standards; it covers both hill climbs and race track based events. Solo I (and Solo II) are time trials; there is no wheel-towheel action involved. Solo II is a moderate speed event; it corresponds roughly to what other clubs call autocross. Safety equipment is not mandated, except for roll bars in heavily prepared convertibles (stock convertibles do not require roll bars in Solo II.
