Vuky, Pancho and JP all seemed like nice guys in addition to being good (if not great) drivers. Tony Bettenhausen, too. Al Jr. has real problems despite seeming to me to have the right attitute (I think the tequila in Mom Unser's famous chili suggests where that issue originates). Michael seems like a pretty sensible and decent guy, despite having a giant stick up his a$$. From all reports I gather Arie Jr. is an okay guy (although I have heard (I think) that his mother can be a real stage-mom b*tch, though no one will name names to let me know if I accuse her wrongfully or not).
All of the above seem relatively humble and nice compared to the current crop.
I know I'm forgetting a ton, but I am in a '60s mood at the moment and can't think of anyone else besides Ludwig Heimrath Jr. (saw his father race in my first-ever pavement Champ Car race) Oh yeah, Johnny Unser, Robby, and Alfred, A J Foyt IV, Anthony Foyt. I think there are issues there with a few of them, but I am not really very familiar with any of them.
But Graham and Marco? They both strike me as having a sense of entitlement and lack of humility that really rubs me the wrong way. Is it just me? Marco turned me off when he had real trouble admitting how stupid his move was that took out both TK and Sarah at Indy in 2008 (and if I'm not mistaken proeceeded to made a similar mistake at Milwaukee the next week that took out several cars), and Graham rarely seems to think he has ever done anything wrong since the day he was born, including the most blatant block of the 21st Century last week. Stand these prima donnas next to Hinch or Newgarden, and you will have three guys telling you how great Graham is and three guys telling you how great Marco is. JMO.
I haven't really thought this on through, but it is a subject that has bubbled around my consciousness since they both came on the scene about six years ago. So I'll ask now. Is it me? Do you see any noticeable pattern in second- and third-generation IndyCar drivers today, and are today's crop different from those that have come before?
