Thanks for the answers to 16D. That was very cryptic! Just a couple more needed please: 27A. Place each name inside ground kernel (6). I think possibly an anagram of "kernel" but not sure. Also 18D. Card's dishonesty (7). I have --a-e-y Finally 17A. Motorist surprisingly said to be free of accidents (8,6). I have "driver" as the second word. You help is much appreciated.
27a PEANUT (p= place; EA=each; NUT=kernel) and peanut is a ground nut
18d KNAVERY (Knave is a card; knavery is dishonesty)
17a (pun on the sound) RECKLESS (ie wreck-less) DRIVER
